There's no magic to automatically take care of what you are trying to
do (unless I've overlooked some very interesting functionality).
If you want to fetch an XHTML snippet from an AJAX request you need
to explicitly return that XHTML by specifying a template containing
that snippet.
If you want to return only the changed values and modify the page
using javascript you could return them as JSON using:
return dict(tg_format='json', data=data)
Cheers,
