On $('#').buttonset() (using radio buttons with labels), the onchange/onclick event is not firing, which means I can't submit the form every time the radio button is clicked. Works fine in Chrome. Not tested in Firefox. Using 1.8 RC3. Not tested with RC2, but changes apparently have been made since then.
edit: Update - I since solved my problem by using asp.net AJAX links rather than radio buttons. This resolution worked in my scenario, but it won't necessarily work in all scenarios. Here is some non-working (not bound) sample code: http://jsbin.com/ijali/edit
