Hi Andrew,
The new .on Handler extension released very recently (I believe within the past week or so, there's a screenshot below of what this new version looks like) will actually do this now. It's based on the "Direct and delegated events" section of the following link:
http://api.jquery.com/on/
Note that this will not work for any elements within an inserted iframe, and it requires jQuery 1.7 or newer. If you tried this very recently and it still does not work, please contact your account manager so we can take a closer look at your specific use-case. Hope this helps!
