How to declare tabs and accordion jquery libraries

Hello,

I try do declare link with a script but I don’t have nothing in source code of pages.

This is the code in functions.php :

function add_custom_scripts() {
	wp_enqueue_script('jquery');
	wp_enqueue_script('jquery-ui-core');
	wp_enqueue_script('jquery-ui-accordion');
	wp_enqueue_script('jquery-ui-tabs');
	wp_enqueue_script('mes_scripts', get_stylesheet_directory_uri() . '/js/messcripts.js', array('jquery') );
}

add_action( 'wp_enqueue_scripts', 'add_custom_scripts' );

What happends ?
