var header = ui.element.find("th[role='columnheader']");
for (var i = 0; i < headerSetting.length; i++) {
var currentSetting = headerSetting[i];
header.filter("th[aria-label='" + currentSetting.key + "']")
.find(".ui-iggrid-headertext").text(currentSetting.headerText)
}
});

$(document).delegate("#igGridLog", "igchildgridcreating", function(evt, ui) {
evt;
var childSource = ui.options.dataSource;
var ds = $("#igGridLog").igGrid("option", "dataSource");
var parentSource = _.isArray(ds) ? ds : ds._data;
var headerSetting = [];
var newSource = [];
if (childSource.length > 0) {
for (var i = 0; i < parentSource.length; i++) {
if (parentSource[i].parentKey === childSource[0].parentKey) {
headerSetting = parentSource[i].subColumnsHeaders;
newSource = _.cloneDeep(parentSource[i].lstLogPerCateCorrectRecordDto);
}
}
ui.options.dataSource = newSource;
$(ui.element).data("headersetting", headerSetting);
}
});

Please help me to fixed it
