    Hi All,

    I has been awhile since I used kendo and I have no idea why my values are not observable. What I am missing when I'm calling a popup html template and no data are showing in the textbox or data are not updated after I modified them.  Any suggestions or an example is much appreciated.




    var rEditor= rEditor || {};

    var rEditor = (function () {
        var kendoViewModel;

        function createViewModel() {
            kendoViewModel = kendo.observable({
                selectedCategoryId: null,
                selectedCategoryDesc: "test description",
                selectedCategoryCode: null,


        function loadData() {
                url: "/sample/LoadCode",
                type: "GET",
                async: true,
                success: function (result) {

                url: "/sample/Loadother",
                type: "GET",
                async: true,
                success: function (result) {                
      function setupResourceDropDown() {
     dataTextField: "Description",
     dataSource: kendoViewModel.Codes,
     change: function () {
     ..filter the data and call


        function setGrid() {
                dataSource: {
                    data: filterCategory,
                    schema: {
                        model: {
                            fields: {
                                Id: { type: "string", editable: false },
                                Code: { type: "string", editable: true },
                                Description: { type: "string", editable: true }
                selectable: "row",
                editable: true,
                columns: [
                    hidden: true,
                    field: "Id",
                    title: "Id",
                    width: 200
                    title: "Code",
                    field: "Code",
                    width: 100
                    title: "Description",
                    field: "Description",
                    width: 300,                
                   title: "test",
                   field: "Code",
                   template: "#=Code#",
                   editor: editCategory,
                dataBound: function (e) {
                    telerikFilterIndicator(e, this);

        function editCategory(container, options) {
            //var model = options.model;
            //kendoViewModel.set("selectedCategoryId", model.Id);
            //kendoViewModel.set("selectedCategoryDesc", model.Description);
            //kendoViewModel.set("selectedCategoryCode", model.Code);

            var editWindow = $("#editResource-dialog").kendoWindow({
                resizable: false,
                title: "Edit",
                modal: true,
                width: "575px",
                height: "185px",
                visible: false


            $("#confirmUpdateButton").click(function () {

            $("#confirmCancelButton").click(function () {

        function init() {
            kendo.bind($("#MainWrapper"), kendoViewModel);


        return {
            Init: init


    <div id="MainWrapper" class="MainWrapperCls">
        <div id="Main" class="row">
            <div class="row">
                <div class="col-lg-1">
                <div class="col-lg-2">
                    <select id="ResourceCode_DropDownMenu" class="form-control"></select>

        <div id="editResource-dialog" title="Resource Editor" type="text/x-kendo-template" style="display: none">
            <div class="modal-body" id="editorWindow">
                <div class="input-group" style="padding-bottom: 5px">

    Hello Steve,

    From the provided information it seems that you are trying to reimplement the Grid build-in popup editor - could you please clarify why you are using this approach? In current setup I would instead suggest to use the Grid build-in popup editor as it will handle the binding automatically. Please check the following example:
