Always trigger switchChange after change

With 2 or more radio buttons, a change to the first radio button propagates correctly,
while the change to the second one won't (as it is always skipepd). This fixes it by
propagating `switchChange.bootstrapSwitch` after every `change.bootstrapSwitch`.
Everything else keeps working.
Build js files.
