[Vala] GtkBuilder example ... bug?

[Jakub Klawiter <jklawiter gmail com>]

Hello!

Newbie has a problem ;-)

Gtkbuilder example:
http://live.gnome.org/Vala/GTKSample#head-e558b6b451800cf5547de009be1435b7f90d8d37
I do want to put signal handlers in separate class, so i did described
changes, and now example looks like this: http://www.nopaste.pl/iaf
but it's not working because:

Gtk-WARNING **: Could not find signal handler 'on_button2_clicked'

so probably there is, a bug in example code. Can I ask where? ;-)
