Header doesn't work!

I made a few layouts for my pages. I choose them during adding new page. Unfortunately, they are displayed on the website with classical layout made for other pages.

In the ‘special layouts’ for some pages I wanted to make different header. I made it by:

<?php
/*
Template Name: PagePortrait
*/
?>	

<?php get_header('portrait'); ?>

<div class="title"><h1><?php wp_title(' '); ?></h1></div>
		<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
		<?php the_content(); ?>
		<?php endwhile; ?>

<?php get_footer(); ?>

and the name of file with header is: header-portrait.php

Why this happens? What should I change?
