I can confirm the example is now working as expected.

I'll try to wrap my widgets this way and see if I can get full Glade3 /
libglade integration (which would really be awesome :)). Thank you for
your help on this!

Btw: having this done automatically would be great, however doing it
this way is fine for now, especially if it would be covered somewhere in
the documentation.
