Is there a way to render a checkbox into an itemTpl? In ST2.1.0, there's no event that fires after the list data is rendered, so I can't post-process with renderTo. I think there has to be a way to render to some fake element and grab the HTML, but I can't figure out anything that works.

I need something like this:

{xtype:'list', itemTpl:'{[renderCheckbox()]}}

Has anyone done anything like this before?
