select control manipulation not working
<p>I am using the jquery live function to create multiple widgets on a page using ...</p>

<pre><code>$('#mybutton').live('click', function(){
var first = $('#win-doors-pvc fieldset:first').html();   
$(first).find('select option:selected').attr('selected',false);   
$('#win-doors-pvc').append('&lt;fieldset&gt;'+first+'&lt;/fieldset&gt;');
});
</code></pre>

<p>The code above successfully re-creates the content within a fieldset.</p>

<p>The content with var first contains a select control.
I would like to manipulate that select by using </p>

<pre><code>$(first).find('select option:selected').attr('selected',false); 
</code></pre>

<p>to de-select what has been selected.</p>

<p>Why does it not work ?</p>
