How to enable sidebar on category page?

I solved it but I don’t know is it right. What do you think about it?

1. I created file category.php with this code:

<?php get_header();?>

<div class="section di_cat <?php echo $section_class; ?>">
	<div class="section_wrapper clearfix">
		<div class="asdasd"></div>
		<div class="column one column_blog">
			<div class="blog_wrapper isotope_wrapperw">

				<div class="posts_group lm_wrapper <?php echo implode(' ', $blog_classes); ?>">
					<?php echo mfn_content_post( false, false, $load_more ); ?>
				</div>

				<?php
					// pagination
					if( function_exists( 'mfn_pagination' ) ):

						echo mfn_pagination( false, $load_more );

					else:
						?>
							<div class="nav-next"><?php next_posts_link(__('← Older Entries', 'betheme')) ?></div>
							<div class="nav-previous"><?php previous_posts_link(__('Newer Entries →', 'betheme')) ?></div>
						<?php
					endif;
				?>

			</div>
		</div>

	</div>
</div>
<?php get_sidebar('sidebar1'); ?>

<?php get_footer(); ?>

2. I created file sidebar-sidebar1.php and put this code:

<div class="asd">
		<div class="di_cats">
            	<?php dynamic_sidebar( 'press' );?>
        </div>
</div>

It’s all. Sidebar appeared on my Category page.
