Combobox(cascading) not calling Method on Controller

[Agropur]

Here is my View:

<div class="form-group">
            @Html.LabelFor(model => model.locationCode, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DropDownListFor(model => model.locationCode, new SelectList(Model.Locations))
                @Html.ValidationMessageFor(model => model.locationCode)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.loadType, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DropDownListFor(model => model.loadType, new SelectList(Model.LoadTypes))
                @Html.ValidationMessageFor(model => model.loadType)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.loadDescrip, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @(Html.Kendo().ComboBox()
                        .Name("loadDescription")
                        .Filter(FilterType.Contains)
                        .DataSource(source => {
                            source.Read(read =>
                            {
                                read.Action("GetCascadeDocumentNumbers", "DockDoor")
                                    .Data("filterLoadDescription");
                            })
                          .ServerFiltering(true);
                        })
                        .Enable(false)
                        .AutoBind(false)
                        .CascadeFrom("loadType")
                        )
                <script>
                    function filterLoadDescription(){
                        return {
                            locCode: $("#locationCode").val(),
                            loadType: $("#loadType").val(),
                            docNumFilter: $("#loadDescription").data("kendoComboBox").input.val()
                        };
                    }
                </script>
                @Html.ValidationMessageFor(model => model.loadDescrip)
            </div>
        </div>

Here is the method in my Controller:

public JsonResult GetCascadeDocumentNumbers(string locCode, string loadType, string docNumFilter)
       {
           var docNums = db.GetCurrentDocumentNumbers(locCode, loadType).AsQueryable();

           if (!string.IsNullOrWhiteSpace(docNumFilter))
           {
               docNums = docNums.Where(x => x.Contains(docNumFilter));
           }

           return Json(docNums.Select(x => new {DocCode = x}), JsonRequestBehavior.AllowGet);
       }

What am I doing wrong that this is not being called?

Hello,

Thank you for the given code snippets. At first glance, the setup of the widgets looks just fine. In order to proceed with the investigation I will ask you to send us a simple repro test project. Thus I will be able to observe the issue locally and advice you further.

Hello ajith,

The shared code is not sufficient to determine why the cascading functionality does not work on your end. Could you send us a repro demo that demonstrates the issue?
