Facebook Comment Count Refresh

Hi,
I’ve implemented facebook comments count with the traditional wordpress comments count, but unlike it the count dosen’t refresh after the comment submission.

I’ve used this function to do it:

// Get combined FB and WordPress comment count
function full_comment_count() {
	global $post;
	$url = get_permalink($post->ID);
	$filecontent = file_get_contents('https://graph.facebook.com/?ids=' . $url);
	$json = json_decode($filecontent);
	$count = $json->$url->comments;
	$wpCount = get_comments_number();
	$realCount = $count + $wpCount;
	if ($realCount == 0 || !isset($realCount)) {
		$realCount = 0;
	}
return $realCount;
}

What can I do? Thanks in advance!
