Kendo Grid loaded via template in window -aggregates returning undefined at runtime

[Brendan]

Hello,

Using the Fluent UI cshtml helpers, I am loading a Kendo UI window, using a template. 

The template contains a grid, for which I utilise aggregates; namely the Sum.

When the window is activated on my page, I receive a javascript error "sum is undefined".

Note: the window is loading a grid of child elements to a parent row of data on the main page's grid. (Hierarchy). 

In my investigations,
 - the template loads the grid correctly and functions perfectly if I do not have aggregates

Any ideas guys?

Thanks,
Brendan

---- TEMPLATE ----
** for brevity, I cut out the .Add(), .Destroy() datasource calls

<script id="MaterialTraceItemsAdvancedTemplate" type="text/kendo-tmpl">
    <div id="details-container">

        @(Html.Kendo().Grid<TraceItem>().Name("grid_#=OID#").Columns(columns =>
          {
              columns.Bound(o => o.Cert).Width(70);
              columns.Bound(o => o.Trace).Width(110);
              columns.Bound(o => o.ExpectedQty).Width(110).ClientFooterTemplate("Sum: #=sum#"); 
              columns.Command(command =>
                  {
                      command.Destroy();
                      command.Edit();
                  }).Width(110);
          }).Editable(editable => editable.Mode(GridEditMode.InLine)).ToolBar(toolbar =>
              {

Hello Brendan,

I believe that the correct template, due to nested grids, should be as follows:
.ClientFooterTemplate("Sum: \\#=sum\\#")

You can find more details here: Escaping Hash Literals.
