add_overdub_listener and add_session_record_listener not working

add_overdub_listener and add_session_record_listener are not working.

– Create a Reaction with session record listener: self.song().add_session_record_listener.
– Log the value of session_record: self.show_message(str(self.song().session_record))

The listener is not firing when session_record is first changed to true. It only fires once a clip previously exists and you are overdubbing but not when recording into an empty clip.
