sample of kendo combo for relation table with id and value - asp.net-mvc-4

Question

i'm using kendo ui in my asp.net mvc 4 with razor views and encounter problem with kendo combo when the list load from an action via ajax with sending parameters to the server like the sample here:HERE
becuase the table has more then 2,000 rows.
when i load the edit page, the combo load and filter the data as expected, but the value of this field is - [object object].
i did declare the .DataTextField("ProffName") + .DataValueField("ID")
My ClientsController:
public ActionResult Edit(int id = 0)
{
Clients clients = db.Clients.Find(id);
if (clients == null)
{
return HttpNotFound();
}
ViewData["MyAgency"] = new SelectList(db.Agency, "ID", "AgentName", clients.AgencyId);
ViewData["MyCategory1"] = new SelectList(db.CategoryTbl, "ID", "category", clients.CategoryId);
List<SelectListItem> obj = new List<SelectListItem>();
obj.Add(new SelectListItem { Text = "male", Value = "1" });
obj.Add(new SelectListItem { Text = "female", Value = "2" });
obj.Add(new SelectListItem { Text = "choose", Value = "0" });
ViewData["MyMin"] = obj;
ViewBag.ProffID = new SelectList(db.ProfTBL, "ID", "ProffName", clients.ProffID);
ViewBag.Metapel = new SelectList(db.Workers, "ID", "WorkerName", clients.Metapel);
return View(clients);
}
My ProffController:
public ActionResult ProffVM_Read(string text)
{
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName });
if (!string.IsNullOrEmpty(text))
{
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text));
}
return Json(Proff_Tbl, JsonRequestBehavior.AllowGet);
}
and the Kendo combo:
#Html.Label("Proff")
#(Html.Kendo().ComboBoxFor(model => model.ProffID)
.Name("proffCbo")
.DataTextField("ProffName")
.DataValueField("ID")
.Events(e => e
.Select("proffCbo_select")
.Change("proffCbo_change")
)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("ProffVM_Read", "Proff")
.Data("onAdditionalData");
});
})
)
where am i wrong ???
i can change this combo to textbox but... i have to realize the magic.
Thanks

Change these two lines
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName });
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text));
to
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName }).ToList();
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text)).ToList();
