If you hang it on the DG, then any click in the row whether on the
checkbox or not will send a change (of selectedIndex)

If you hang it on the checkbox, then a change to the selected state of
the checkbox will trigger your code.

 

How are you trying to get the change handler on the checkbox?

Just to be clear, should I be monitoring a change on the datagrid, or 
the checkbox? If it's supposed to be on the checkbox, I'm in trouble 
because it's not letting me put in a change="processmyChange" handler 
on it.
