Embedding a short code in a custom template

I am trying to embed a short code in a custom template that I created for a page. The custom template simply has the following code

Template Name: Contact-Form


<?php get_header(); ?>

<?php get_footer(); ?>
As expected, this gives me a blank page with the header and footer. Now , In the Wysiwyg area of the post, when I put the short code for my contact form as [bws_contact_form lang=en] , it does not show the contact form. The contact form plugin I am using is https://premium.wpmudev.org/project/contact-widget/#usage .

Please can you let me know what I am doing wrong ?
