Under 4.1, we had a Dynamic Action using a jQuery selector on Change of table.radiogroup.
This would fire whenever the end user clicked a radio button and, thus, changed the value. It also fired on Page Load.
Under 4.2, it simply doesn't fire. Even if I remove all JS and just put an alert, the event is no longer being fired. I have confirmed that it is still table with class of "radiogroup" So; "table.radiogroup" should still work as my jQuery selector. By the way, I also tried Clicked and GetFocus but, none of these would fire either.
