This was a bug, which is now fixed.  Looking at this reminded me that I 
gave [textbox] a type which allows mixing of traditional forms with 
reactive client-side stuff, while none of the other widgets has a 
similarly permissive type.  It's probably worth rationalizing the whole 
set of widgets along these lines at some point, but at least your 
example works (for me) now.
