Paging Sorting Not Working

[Jack]

Hi to all Members.I have installed Kendo and i am using a very basic Grid
I have bind it successfully but paging sorting doesn't seems to Work

This is my View
@model IEnumerable<UserManagementApplication.Models.tblUser>
@{
    ViewBag.Title = "GetDataKendo";
}
<h2>GetDataKendo</h2>
   
@(Html.Kendo().Grid(Model)  
    .Name("Grid")
     .Columns(columns =>
      {        
          
          columns.Bound(model => model.FirstName);
          columns.Bound(model => model.LastName);
          columns.Bound(model => model.EmailAddress);
          columns.Bound(model => model.IsActive);
      })
      
    .Pageable()
    .Sortable()
    .Filterable()
    .Scrollable()
    .Groupable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("GetUserDataKendo", "User")
        )
    )
)

And this is my Controller Method
 public ActionResult GetUserDataKendo([DataSourceRequest]DataSourceRequest request)
        {                   
            
            var displayedEvents = client.GetUserList(1, 100, "", false, "");      
           var result = new DataSourceResult()
            {
                Data = displayedEvents
            };
            return Json(result);
        }
