You have somehow broken GTK+.... updates in GTK+ are supposed to 
just work, so there is no function to call "make updates work".

If you can create a small standalone test, it would be worth filing a
bug.

I don't think those functions do what you think they do... unless you
are implementing a container widget, there should be no reason to
call them (though I wouldn't expect them to have much effect one way
or the other.. notification of child properties is basically there for
GUI builders.) Removing these calls would be the first step to take.
