[maemo-developers] hildonpickerdialog done button

[From: Michael Cronenworth]

How does one attach to the "Done" button when using two 
HildonTouchSelector columns? When I press the button nothing happens. 
I'm using single selection mode. I have two columns of regular text 
(numbers). I select two numbers and press "Done" but no action occurs 
and I do not see any signal to attach to in the reference docs.

Thanks,
Michael
