Custom filter (Excel)


Trying to implement Excel filtering and almost evertyhing works fine apart suggestions in custom filter textfield. My current return format from backend for grid (json) is:
{ result: [{}, {}, {} ..], count: 0 } - I see that by my request, I do return those records, but suggestion list can't find anything. Do I need different return format? If yes, how do I know which format to return when it's for Grid and Suggestions list? When I stop typing in textfield, it makes this request:

Hi Customer, 

Thank you for contacting Syncfusion support. 

To overcome this problem, we suggest you to return records alone in server side when dm.RequiresCounts as false for display autocomplete suggestion list. Please refer to the below code example. 

 public ActionResult DataSource(Syncfusion.JavaScript.DataManager dm) 
            IEnumerable Data = OrderRepository.GetAllRecords(); 
            Syncfusion.JavaScript.DataSources.DataOperations operation = new Syncfusion.JavaScript.DataSources.DataOperations(); 
            if (dm.Sorted != null && dm.Sorted.Count > 0) //Sorting 
                Data = operation.PerformSorting(Data, dm.Sorted); 
            if (dm.Where != null && dm.Where.Count > 0) //Filtering 
                Data = operation.PerformWhereFilter(Data, dm.Where, dm.Where[0].Operator); 
                if (!dm.RequiresCounts) 
                    return Json(Data); //Return records alone for the autoComplete list 
            int count = Data.AsQueryable().Count(); 
            if (dm.Skip != 0) 
                Data = operation.PerformSkip(Data, dm.Skip); 
            if (dm.Take != 0) 
                Data = operation.PerformTake(Data, dm.Take); 
            return Json(new { result = Data, count = count }, JsonRequestBehavior.AllowGet);
