I'd like to refresh dynamically a fb:like plugin into my page.

For exemple, into index.html, I have :

```
<fb:like id="fbtest" href="http://www.urltest.com" send="true" width="450" show_faces="true"></fb:like>

```

(Facebook is initialized, and all works perfectly.)

Then, I'l like to change dynamically the URL of this like button.
So, with jQuery, I do :

```
$('#fbtest').attr('href', 'http://www.urltest2.com').empty().off().removeData();
FB.XFBML.parse();

```

And it's doesn't work... It only work when I **remove** the fb:like tag, and recreate it (exactly the same DOM !). 

As you can see here: [Update FB:Like URL Dynamically using JavaScript](https://stackoverflow.com/questions/2764129/update-fblike-url-dynamically-using-javascript) ,
All methods described recreates the fb:like tag... I need to **refresh** an existing fb:like... not recreate it. Is it possible ?

EDIT : Here's a fiddle for testing :-) : <http://jsfiddle.net/nRTkS/>

Thanks!
