title: Parent data text field not recognized in Kendo TreeView when using data attribute initialization
body: <p>I'm trying to using Kendo TreeView with attribute data initialization, following <a href="http://docs.kendoui.com/getting-started/data-attribute-initialization" rel="nofollow">the official documentation</a> . As far as I understand, the next two portions of code should be equivalents:</p>
  
  <p>1.- data attribute initialization style:</p>
  
  <pre><code>  &lt;div id="treeview-right" 
               data-role="treeview" 
               data-source="inline"
               data-text-field="['categoryName', 'subCategoryName']"&gt;
    &lt;/div&gt;
  </code></pre>
  
  <p>2.- JQuery style:</p>
  
  <pre><code>&lt;script&gt;
              $("#treeview-right").kendoTreeView({
              dataSource: inline,
              dataTextField: ["categoryName", "subCategoryName"]
              });
  &lt;/script&gt;
  </code></pre>
  
  <p>The way number 2 works as expected, but the number 1 renders the tree but without the parent node's text(showing 'undefined' text, like it doesn't recognize the 'categoryName' parameter from data-text-field value. By the way , when I set data-text-field to <code>data-text-field="['categoryName']</code> it shows the parent node text, but not the child node's text, as expected. I'm using <a href="http://demos.kendoui.com/web/treeview/local-data.html" rel="nofollow">the example</a> from the official tutorial (JQuery style initialization), if someone wants to see the whole code. Is it correct my supposition?.</p>
