'ref' buttons by classname (in a controller)

[jeanluca]

Hi

I have two logout buttons (each on a different panels), for which I want to do something when they're tapped. I have added a class value of 'logout' to both of them and the following controller setup:

       .....
       ref: {
             logoutButtons: 'button[class~="logout"]' // should match both buttons
       },
       control: {
            logoutButtons: {
                  tap: 'onLogout'
            }
      }
      ....

Well, this doesn't work, any suggestions how to fix this ?

Thanks
Luca
