[Vala] signals again

["Arley Consuegra Rosello" <aconsuegra estudiantes uci cu>]

Thanks to Frederik for the previous answer but now I have a new trouble.

I have two RadioButton each one with the signal clicked active in the glade file.
radio1 ---> mostrar_asistente_dhcp
radio2 ---> mostrar_asistente_samba

radio2 belongs at the group of radio1.
When I clicked radio1 the Assitant for dhcp appears and it is ok, but when I clicked radio2 appears the 
Asistnat for dhcp and the Asistant for samba.
What is wrong?
