Can't full width the sing job listing

Hi, I tried to remove the sidebar in single job, I created a new template (single-job_listing.php) and put this code

<div class="ak-container">
	<div id="primary" class="content-area">
		<main id="main" class="site-main" role="main">
			<?php while ( have_posts() ) : the_post(); ?>

				<h1 class="entry-title"><?php the_title(); ?></h1>

					<div class="entry-content">
						<?php the_content(); ?>
					</div><!-- .entry-content -->
			<?php endwhile; // end of the loop. ?>
		</main>
	</div>

<?php
	//get_sidebar('left');
	//if ($post_class=='both-sidebar') { ?>
			</div>
	<?php //}
	//get_sidebar('right'); ?>
</div>

<?php get_footer(); ?>

but it’s not working
