How to Bind Data to kendo grid by passing date from kendo datepicker?

I am new in Kendo UI, I have one kendo DatePicker and one Kendo GridView. After selecting a date from DatePicker according the data should bind to the Kendo GridView. I use jquery with Ajax and my jquery function is

List<MDA.AppEntities.Orders.OrderList> objConsults = new List<MDA.AppEntities.Orders.OrderList>(); 
objConsults = DataFacade.Operations.GetCustomerOrderDetailsByCustomerID(Patientid,startDate,en‌​dDate ); 
return new PrimeJsonResult { MaxJsonLength = int.MaxValue, JsonRequestBehavior = JsonRequestBehavior.AllowGet, Data = new GridModel<MDA.AppEntities.Orders.OrderList> { Data = objConsults } };

It is going inside success: function(data), but not executing inside code and jump back to $.ajax(), and I don't understand why.
