.NET 4.6, MVC 5

$(document).ready is not fired on any page using a view that is returned from a controller using @Html.ActionRender I know that some Infragistics component is the culprit, and I expect it to be the igLoader, but not quite sure.

I don't see any errors regarding jquery missing, or resources not found. window.on('load') does get triggered, issues started happening right after I tried to render the subview

There are no issues whatsoever when I run my subview. The weird reason is that sometimes it works, sometimes it doesn't. It depends on the ammount of data that needs to be rendered (depends on data in database, dependent on model and entityname parameters)

As you can see in the code below I have already added alrts as well to be sure that doc.ready is not called. The alerts inside the script tags work, but not the ones when I test for document.ready

As stated by the documentation the igLoader has to be included on each page, even partial views when using the mvc helper, which I do

MainController Action

public ActionResult Index(string modelName, string entityName, string view, string cs)ityName){
	//generation of grid features is the same for each grid
	//columns depends on which modelName and entityName + datatype, dynamic database dependent on client
	//returns view with a model which has a property *.GridModel which is the generated gridmodel to be used in the view
})

Stripped down Main View with issues

@using Infragistics.Web.Mvc
@model Factstone.Web.Models.Views.MemberVm
@{
    ViewBag.Title = $"{Model.EntityName}";
    Layout = "~/Views/Shared/_Infragistics.cshtml";
    const string gridId = "grdMember";
    const string frmMemberId = "frmMember";
    const string btnMemberAddId = "btnMemberAdd";
    const string btnMemberSaveId = "btnMemberSave";
    const string btnMemberCancelId = "btnMemberCancel";
    Model.GridModel.ID = gridId;
}

Another View which uses the subview defined below, but which does work as intended
