It looks like you are trying to emit the edited signal here without
specifying the correct arguments.

Maybe you can try using gtk_cell_editable_editing_done() here?  The
editing-done signal handler of the respective cell editable will take
care of emitting the edited signal.  You can get hold of the correct
cell editable by listening for the editing-started signal on the cell
renderer.
