Update value of multiple selectpickers via class

[klibansky]

I have 2 select tags both with the same class (.expiry2) and I want to set then both with the same value via: $('.expiry2').selectpicker('val', 'some thing');
Only the first instance gets updated and not the second.

Could you provide a jsfiddle or bootply?
