Perspective Table Checkbox:: get state for update query within onEditCellCommit event

I have a boolean value coming in from SQL (bit) and rendering it as a checkbox. On the edit I am having a hard time getting the value off of the checkbox to pickup that state change (true,false,checked, unchecked, 1,0 etc).

IsApproved =, ‘IsApproved’)

does not seem to give me a value on an edit.
Any ideas or questions I can answer to help clarify? Thanks in advance.
