Grid Custom Server Binding Data

Group statistics have no data ,ClientGroupHeaderTemplate()  do not work;

GroupHeaderTemplate(g=>g.Count),g.Count is Null

Custom Server Binding  the way How to implement group statistics?

 

Examples Code:

@model System.Collections.IEnumerable
@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.Order>()
    .Name("Grid")
    .EnableCustomBinding(true)
    .BindTo(Model)
    .Columns(columns => {
        columns.Bound(o => o.OrderID).Groupable(false);
        columns.Bound(o => o.ShipCity).GroupHeaderTemplate(g=>g.Count);
        columns.Bound(o => o.ShipCountry).ClientGroupHeaderTemplate("ShipCountry: #= value # (Count: #= count#)");
        columns.Bound(o => o.ShipName);
    })
    .Pageable()
    .Sortable()
    .Filterable()
    .Scrollable()
    .Groupable()
    .DataSource(dataSource =>dataSource
        .Server()
        .Total((int)ViewData["total"])
        .Aggregates(aggregates =>
            {
