Issue with Kendo Paging (Shows always 1) when Ajax binding and Server Operation

Question

I am currently working on Kendo Grid and wants to perform all operation server side.

For now, everything is working, except, when I call Read action and find the correct page number, and set it on the DataSourceResult, the object is found on the Grid, Selected and Highlighted as expected, but the UI Pager value always shows 1 or set to 1, no matter what Page value I have set in the DataSourceResult.

Below is my cshtml code:

@(Html.Kendo().Grid<dynamic>()
      .Name($"Grid_{Model.Name}")
      .Columns("Some Columns")
      .Pageable(Model.Pager)
      .Filterable(ftb => ftb
         .Mode(GridFilterMode.Row)
      )
      .DataSource(dataSource => dataSource
         .Ajax()
         .Read(read => read.Action("GetBrowseResults", Model.Controller, new { area = string.Format("Module/{0}", Model.Controller), theTypeToBrowse = Model.TypeToBrowse, theGroupObj = Model.IsGroupType }))
         .PageSize(Model.IsTouchDevice ? 20 : 100)
      .ServerOperation(true)
      )
      .Events(events => events.Change("LibraryRecordSelected").DataBound("LibraryDataBound"))
)

And here is the C# code:

public ActionResult GetBrowseResults([DataSourceRequest] DataSourceRequest theRequest, string theTypeToBrowse, string theGroupId, bool theGroupObj)
      {
         var browseResult = GetBrowseResults(theTypeToBrowse, theGroupId, theGroupObj);

         if (browseResult != null)
         {
            var ret = FilterBrowseModel(browseResult, theRequest);
            var result = Json(ret.Item1.ToDataSourceResult(ret.Item2));
            result.MaxJsonLength = int.MaxValue;
            return result;
         }
      }
          
public (List<BrowseModel>, DataSourceRequest) FilterBrowseModel(IEnumerable<BrowseModel> theBrowseModel, DataSourceRequest theDataSourceRequest)
      {
         var ret = new List<BrowseModel>();
         int total = theBrowseModel?.Count() ?? 0;

         if (total > 0)
         {
            bool reset = true;

            if (theDataSourceRequest.Page > 0 && theDataSourceRequest.PageSize > 0)
            {
                  var objectData = GetObjectData(HttpContext.Request.RequestContext.RouteData.Values["controller"].ToString());
                  if (objectData?.ObjectTxt != null)
                     theDataSourceRequest.Page = (theBrowseModel.ToList().FindIndex(x => x.ObjectTxt == objectData.ObjectTxt)) / theDataSourceRequest.PageSize + 1;
            }

            if (reset)
               ret.AddRange(theBrowseModel);
         }

         return (ret, theDataSourceRequest);
      }
