    Below you can see the pertinent code.  when I try to append a new node in the tree it's always "undefined" when I check $("#appendNodeText").val() it does have the correct value.  What am I missing?

                                    .HtmlAttributes(new { @class = "col-md-6", id = "treeview" })

                        .DataSource(dataSource => dataSource
                            .Read(read => read
                                .Action("Categories", "DisplayArticle")
                        .Events(events => events

            <input id="appendNodeText" value="Node" class="k-textbox" />
            <button class="k-button" id="appendNodeToSelected">Append node</button>

        var treeview = $("#treeview").data("kendoTreeView"),
            handleTextBox = function (callback) {
                return function (e) {
                    if (e.type != "keypress" || kendo.keys.ENTER == e.keyCode) {

            var append = handleTextBox(function (e) {
                //var treeview = $("#treeview").data("kendoTreeView")
                var selectedNode =;

                // passing a falsy value as the second append() parameter
                // will append the new node to the root group
                if (selectedNode.length == 0) {
                    selectedNode = null;
                    Name: $("#appendNodeText").val(),
                    id: $("#appendNodeText").val(),
                    text: $("#appendNodeText").val()
                }, selectedNode);

    Hello Wyatt,

    The TreeView is configured to use the Title field (through the DataTextField("Title") invocation). Thus, when appending items, you should specify that field instead of the default one (text). 

           Title: $("#appendNodeText").val()
        }, selectedNode);

                Name: nodeText,

                id: nodeValue

            }, selectedNode);
