Maybe you are not setting the new value in the model when the check box is
clicked. You need to not only set the cell to editable/activatable, but
respond to the edit/activate action and use (maybe after validating) the
new value. You should find examples of this in various programs, or you
can read the implementations of the add_column_editable() methods, which
also do this.
