<div data-role="grid" id="IGrid"
                data-editable='true'
                data-columns='[
                { "field": "Description", title: "Description"},
                {
                  "field": "OriginalAmount", title: "Amount", width: "100px",  editable: function () {  return false; }, template: kendo.template($("\\#GstAmount").html()),
                   footerTemplate: "Total: #=sum#")
                },
                {command:[{name:"destroy"}]}
                ]'
                data-bind='source: GST.GSTBreakup ,events: {dataBound: parent().GridDataBound}'
                style="height: 200px"></div>

Hello, Neeraj,

The described behaviour is expected for MVVM bound grids as they are created with an empty data source initially which is without aggregates. This is explained in detail in the documentation:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.footertemplate

The solution is to provide a condition in the template, e.g.:

{ "field": "OriginalAmount", "footerTemplate": "Total: #: data.OriginalAmount? kendo.toString(sum, \"c2\"): 0 #" }

The template above will also show the sum formatted as currency with the help of the kendo.toString() method:
