You need to understand more about how Gtk (and most other GUI systems)
works.

There is a main event processing loop (Gtk.Main.Main), that runs in
one task. It handles all keyboard and mouse events, dispatching to the
event handlers you have defined. If you start another task, that
event processing loop is suspended, so nothing happens. It's actually
more complex than that, but that's the basic idea.

Perhaps if you tell us more about why you think you need a second
task, we can help you figure out a better way to do it.
