Thanks.  I glanced at the gtk-demo code too fast, and failed
to understand that it is necessary to attach a callback to the
"toggled" and "edited" signals in order to save the user's changes
in the model.  Without such a callback, the changes are lost...

That was a bit surprising, because a somewhat similar widget like
GtkEntry does not need a callback to be editable and to keep the
user's changes.  Oh well.
