Javascript loading problem

Hello,

I’m trying to make my own WP theme, but the problem is that javascript is not working.
Here is part of my code in header.php file:

<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.easing.js"></script>
<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.vticker-min.js"></script>

and in functions.php

<?php
if( !is_admin()){
   wp_deregister_script('jquery');
   wp_register_script('jquery', ("https://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.js"), false, '1.4.1');
   wp_enqueue_script('jquery');
}

I think my code is right, but none of javascript is loading. In my html template js is work fine.

Where is the problem?
