I need a simple demo of how to launch and close a YouTube video in a [Twitter Bootstrap Modal](http://twitter.github.com/bootstrap/javascript.html#modals) from JavaScript (rather than an anchor tag click).

So far I can launch it just fine, but on close it keeps playing in the background.

Here's my html:

```
<div id="myModalThumbnail"><img src="http://placehold.it/250x150&text=Video%20Thumbnail">
</div>

<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    </div>
    <div class="modal-body">
        <iframe width="520" height="390" frameborder="0" allowfullscreen=""></iframe>
    </div>
</div>​

```

Javascript:

```
$('#myModalThumbnail').click(function () {
    var src = 'http://www.youtube.com/v/KVu3gS7iJu4&amp;rel=0&amp;autohide=1&amp;showinfo=0&amp;autoplay=1';
    $('#myModal').modal('show');
    $('#myModal iframe').attr('src', src);
});

```

And a [jsfiddle](http://jsfiddle.net/VtKS8/5/): <http://jsfiddle.net/VtKS8/5/>

What next?
