Describe the bug

When selecting a category in TreeView mode, the page refreshes, the categories disappear and the questions are not filtered.

To Reproduce

Steps to reproduce the behavior:

1. Create a few categories
2. Create a few questions in those categories
3. In the module settings, choose TreeView for the categories display
4. On the module view, click a category
5. The page refreshes, the categories disappear and the questions are not filtered

Expected behavior

• The selected one should be highlighted
• The questions should be filtered to show only the ones in the selected category

Error log

No errors are logged in the browser javascript console or the Dnn Admin Logs

The issue only happens in edit mode, probably an issue with the Telerik control, since this will be probably replaced by a non-telerik control, I will close that issue since it does not affect users
