How do I get to translate a text within .js like that line?

Hi folks,
How do I get to translate with qtranslate a text within .js code like that line:

$('#ss_account_submit').val('Create Account!');

I tried a lot of things with my low knowledge in Php that didn’t work, such as:

$('#ss_account_submit').val('[:pt]Crie uma conta![:en]Create Account!');

$('#ss_account_submit').val('<--:pt-->Crie uma conta!<--:--><--:en-->Create Account!<--:pt-->');

$('#ss_account_submit').val __(('<--:pt-->Crie uma conta!<--:--><--:en-->Create Account!<--:pt-->'));

$('#ss_account_submit').val (<?php __('<--:pt-->Crie uma conta!<--:--><--:en-->Create Account!<--:pt-->') ?>);

Any idea what could work for this original line?

$('#ss_account_submit').val('Create Account!');

Thanks
