Also, I've just find a solution... The js include code is correct, but it must be written before the last part of code in template.php, ... see below (I still don't know why, what's the reason?):
Code:
<div id="sidebar">
<div class="section">
<?php get_i18n_component('sidebar'); ?>
</div>
<div class="section credits">
<p><?php echo date('Y'); ?> - <strong><?php get_site_name(); ?></strong></p>
<p>
Cardinal Theme by <a href="http://www.cagintranet.com" >Cagintranet</a><br />
<?php get_site_credits(); ?>
</p>
</div>
</div>
