dataTable可选事件

Question

I have a data table set up such that selectionMode="multiple"and I wind up with a column for checkboxes. I have 2 ajax events keying off of rowSelectCheckbox and rowUnselectCheckbox that fire off whenever any of the checkboxes are toggled on or off. My problem is that these ajax events are not firing off for the unique checkbox in the header that selects/unselects all other checkboxes in mass. Is there a way I can disable this checkbox or is there a different event I can tell ajax to look for?
