"Browse the list" and WPML translation plugin

Hi, I need to redirect users the their language “request a quote”‘s page using WPML plugin.
It still redirect on first language page setup on backoffice.
I’e tried to modify add-to-quote.php page using:

<?php if ( ICL_LANGUAGE_CODE=='it' ) :
 		$rqa_url = "/richiedi-preventivo/";
 	else:
 		$rqa_url = "/en/request-a-quote/";
 	endif;

but It works only if I refresh the page. I think because the first link is generated by Ajax…

Someone can help me?
