**Describe the bug**
When a UI is already generated with GenUI, and then I go to the catalog and make a change to the catalog item, I need to do a restart of the app to get the new UI changes visible.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to your project that already have GenUI installed and implemented, with a catalog of custom widgets.
2. Change some elements of the UI for the widget.
3. Hot reload your app.
4. You will see that your UI is not updated.

**Expected behavior**
When I make a UI change to my widgets, I expect that hot reload should work.
