Extending login widget template

Hi!
I am looking to extend template files in order to safely add code to it, but there is where i get stuck.
I did extend this file:
..wp-content/plugins/login-with-ajax/widget/divs-only/widget_out.php
to this path:
..wp-content/themes/MY-THEME/plugins/login-with-ajax/widget/divs-only/widget_out.php

But i cant seem to be able to call my template using this:
<?php login_with_ajax(array("template"=>"divs-only")); ?>
or this
<?php login_with_ajax(array("template"=>"plugins/login-with-ajax/widget/divs-only")); ?>

I can’t seem to work this out. What did I miss?
Thank you.
