Kendo Combo-box inside Kendo Grid MVC shows "No data found" and does not hit the server endpoint

[Somi]

Hi,
   I am working with Kendo UI grid in ASP .NET MVC using an EditorTemplate with ComboBoxFor inside the grid.

Issue description

• The combobox appears inside the grid edit mode.
• When I click the dropdown , it shows "No data found"
• The server side action method is not being hit at all.
• No JS error
• Using same server endpoint DropdownListFor works correctly and loads data

Sample code

@model Department

@(Html.Kendo()
.ComboBoxFor(m=>m)
.DataValueField("departmentId")
.DataTextField("departmentName")
.DataSource(ds=>ds.Read(read=>read.Action("GetDepartments", "Home")))
)
