The problem was other facebook plugins in my site..
Now it's good!

<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#appId=182045851815400&amp;xfbml=1"></script>
<fb:comments width="500" title={$story.news_title} notify="true" reverse="0" publish_feed="1"></fb:comments>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({appId: '182045851815400', status: true, cookie: true,
xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
