The dictionary you're returning just has your count, doesn't it? And where
does the view find "item"?
Secondly, the multiple forms each need to have a separate name, or the
buttons won't know what they belong to.
Thirdly, it usually is easier to use SQLFORM for this (which takes care of
having the rows all displayed, and can handle the remove button, Unless
there is some additional special reason for the way you are doing things,
I'd look into SQLFORM.
