I am having the same issue but with a partial view but can't seem to get it to work no matter which way i do it i get undefined is not a function.  I am calling the partial view from button click in ajax and passing an id that is used in the query to build the queryable list.

Main view:

@using Infragistics.Web.Mvc

@model NOMISe.eSIMON.Web.UI.Areas.Admin.Models.SystemFeatureViewEditModel

@{
ViewBag.Title = "Index";
}

@(Html.Infragistics().Loader()
.ScriptPath("../Scripts/infragistics/js")
.CssPath("../Content/infragistics/css")
.Render()
)

@(Html.Infragistics().ComboFor(feature => feature.AvailableFeature.FirstOrDefault().Name)
.ID("featureSelect")
.Width("150px")
.DataSource(Model.AvailableFeature.AsQueryable())
.CaseSensitive(false)
.ValueKey("ID")
.TextKey("Name")
.FilteringCondition("contains")
.FilteringType(ComboFilteringType.Local)
.RenderMatchItemsCondition(ComboRenderMatchItemsCondition.Contains)
.DataBind()
.Render()
)

//
$(function () {
$("#getDetails").click(event, function () {
var value = $("#featureSelect").igCombo("value");
$.ajax({
type: 'GET',
url: '@Url.Action("GetFeatureSecurities", "SystemAdmin")',
data: { "id": value },
success: function (data) {
$("#featureSecurityList").html(data);
},
error: function () {
$("#featureSecurityList").html("

There was an error.

");
}
})
})
})
// ]]>

Controller section that if fired

public ActionResult GetFeatureSecurities(string id)
{
ObjectSecurityDTOModel viewModel = new ObjectSecurityDTOModel();

IEnumerable securityList = from o in objectSecurityService.FindByObjectID(new Guid(id))
select new ObjectSecurityDTOModel.ObjectSecurityDTO
{
ID = o.ID,
RoleName = "",//o.Role.Name,
//SecurityMask = o.SecurityMask,
AllowDeny = o.Granted,
CreateBy = "",//o.CreatedBy.DisplayName,
DateCreated = o.DateCreated,
ModifiedBy = "",//o.ModifiedBy.DisplayName,
DateModified = o.DateModified
};

viewModel.ObjectSecurityDTOs = securityList;

return View("_FeatureSecurityList", viewModel.ObjectSecurityDTOs.AsQueryable()); //.ObjectSecurityDTOs.AsQueryable()
}

#endregion

//
// GET: /Admin/SystemAdmin/
public ActionResult Index()
{
SystemFeatureViewEditModel viewModel = new SystemFeatureViewEditModel();

SetupFeatureList(viewModel);

return View(viewModel);
}

Partial view:

@using Infragistics.Web.Mvc;

@model IEnumerable

@(Html.Infragistics().Loader()
.ScriptPath("../Scripts/infragistics/js")
.CssPath("../Content/infragistics/css")
.Render()
)

@(Html.Infragistics()
.Grid(Model.AsQueryable())
.ID("featureSecurities")
.Columns(column =>
{
column.For(x => x.ID).HeaderText("ID").DataType("string").Hidden(true);
column.For(x => x.RoleName).HeaderText("Role Name").DataType("string");
//column.For(x => x.SecurityMask).HeaderText("Security Mask").DataType("int");
column.For(x => x.AllowDeny).HeaderText("Allowed/Denied").DataType("bool");
column.For(x => x.CreateBy).HeaderText("Created By").DataType("string");
column.For(x => x.DateCreated).HeaderText("Date Created").DataType("date");
column.For(x => x.ModifiedBy).HeaderText("Modified By").DataType("string");
column.For(x => x.DateModified).HeaderText("Date Modified").DataType("date");
})
.Features(features =>
{
features.Filtering();
features.Selection().Mode(SelectionMode.Row).MultipleSelection(false).Activation(false);
})
.Width("75%")
.Height("325px")
.PrimaryKey("ID")

.DataSource(Model.AsQueryable())

.DataBind()
.Render()
)

 I remebered that i couldn't have datasource set if i passed the data at .Grid().  One error is in my code saying undefiend is not a function and the other is in the infragistics/js/modules/infragistics.ui.grid.framework.js:25.

I am not sure what combination of changes finally got the grid to show but it now shows and returns data.  I did have it just as my viewModel returning and not a list and it never would return.  But i changed it to a list of users and it worked just fine.  Thank you for the help this was starting to get to me that i couldn't get it to work correctly but knew it had to be how i was returning the data or some combination of that and incorrect references to the scripts.  Again thank you very much.

So i changed it to the MVC 4 dll and used it in my MVC5 app and get the following.  More confused about IgniteUI than before, and really hoping the new documentation is released soon as i have no idea why MVC5 dll throws the undefined function error and the MVC4 throws this error.

Server Error in ‘/’ Application.

Yeah i forgot to add more data about version etc i am using.  I am using MVC 5/EF6.1.1/jquery 2.1.1/ jqueryui 1.10.4.  I can try and use the MVC 4 dll instead of the MVC 5 dll and see if it works which would then indicate that there is an issue with the MVC 5 dll

So i verified all my css/js files are in the correct location.  I added the loader() to my _layout.cshtml file so that it will dynamically load for the whole site but i am still getting undefined function error.  Is there a better way to be setting up the grid or is this an issue with 2014.1?

Do you guys have a Nuget package for licensed copies?  I only ask because having a nuget we could install would eliminate some of the issues of having to make sure we have everything manually installed and that it would put things in the proper locations from install.

Still throwing the error.  I am also using a local copy verse the cdn but i am not sure if that has any play on it either.  In my layout i call the loader.js, i did see that you call @(Html.Infragistics.loader()) is that also needed?  If so i will have to get that added to the page also will have to make sure all the css needed is added to the project.
