Comment (by ericlewis):

 `wp.customize.UploadControl.rerender()` can be dropped in lieu of clearing
 out the container ( `.html('')` ) in wp.customize.Control.render, and
 using event delegation on the control (`$container.on( 'click', '.thing'
 ... )`) rather than binding directly to the elements.
