@philfreo I know... this is not a common pattern on this project, but also the List editor doesn't follow exactly the same pattern as the other editors.
Once you have inserted the form element into the DOM, a second call to ```listEditor.render()``` instead of updating the current element, will create a new one... this one new is not possible to trap or handle in any of the available events (there's no post-render trigger or something).  So, this was the most viable solution I found =).
