You should describe your status if you want to get useful advice. Like
mention what is failing.

It must be an instance method to have an instance pos. So it must be inside
the class.

This makes no sense. 'delegate' defines a delegate *type*, but you are
defining a function here.

Oh, and you don't need instance_pos = -1 when you connect things yourself,
because vala will create appropriate wrapper automatically. It is only needed
for the Builder.connect case, where it cannot know to create them.

It's hard to help you when you didn't write whether you have compilation
problems, or wheter Gtk.Builder is complaining that it cannot connect
something or what.
