How to make .sticky working here?

Hello guys,

I’ve got this little problem with .sticky and my theme… ehrrrm let me cut it short: sticky won’t work ??

I’ve got this here in my home/index.php to display the latest posts:

<?php get_header() ?>
<div id="container">
<div id="content">
<ul class="latest">
<?php $feature_post = get_posts( 'category=1&numberposts=4' ); ?>
<?php foreach( $feature_post as $post ) : setup_postdata( $post ); ?>
<?php if (function_exists('c2c_get_custom')) : ?>
<?php endif; ?>
<li class="list-title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permalink <?php the_title_attribute(); ?>"><?php echo ShortenText(get_the_title()); ?></a></li>
<?php endforeach; ?>
</ul>

So does anyone have tips for me to get .sticky working here. ?

Thanks in advance.
