Ajax toggle button for featured posts?

Hi guys!

I would like to add a toggle button in my edit-posts page which will update custom field ‘featured’ by simple click while displaying list of my posts.
The problem is I am not good with ajax…

So far I have created a custom column for my custom post type by adding this code to functions.php:

add_filter('manage_edit-nekretnine_columns', 'my_columns');
function my_columns($columns) {
    $columns['izdvojena'] = 'Izdvojena';
	unset($columns['custom-fields']);
	unset($columns['tags']);
    return $columns;
}

add_action('manage_nekretnine_posts_custom_column',  'my_show_columns');
function my_show_columns($name) {
    global $post;
	switch ($name){
		case 'izdvojena':
			//HERE I NEED TO DISPAY AN IMAGE OF A STAR, BY CLICKING THAT IMAGE POST IS EITHER FEATURE POST OR IS NOT!
			break;

	}
}

Can anyone help me please? For you ajax gurus out there I am sure this is fairly simple… I have been looking into several plugins that have the similar functionality (admin management xtended toggles post visibility on or off), but haven’t been able to do this myself.

Thanks!
