smartSelect change dinamically search and back text for localisation

Hi is possible to change the text of back and search in smartselect dinamically?

I tried

But no success.

Catch pageInit event (solution was on old forum) then change values using
Dom7 $$() methods

Ok, in reality it work perfectly fine independently of pageInit.
Only I made a mistake: it needs to be attached to the tag “a” and not to "select"
