set select option back to default selected
<p>I'm trying to set the select option back to the "choices" every time I finish adding a new row. How can I do it here? Please help. Btw, adding new row(s) works just fine. Here is what I've got so far:</p>

<pre><code>$(document).ready(function() {
   $('#Add-btn').live('click',function() {
      $("#tabName tr:last").before("&lt;tr&gt;&lt;td class='greyed'&gt;&lt;input type='hidden' name='allele' value='" + a + "'&gt;" + a + "&lt;/td&gt;&lt;td&gt;&lt;input type='button' class='delete' value='Remove'&gt;&lt;/td&gt;&lt;/tr&gt;");
   });
});
</code></pre>

<p>HTML:</p>

<pre><code>&lt;table id="tabName"&gt;
...
&lt;select size='1' id="a" name='a'&gt;
   &lt;option value="None" selected&gt;choices&lt;/option&gt;
   &lt;option value='1'&gt;first&lt;/option&gt;
   &lt;option value='2'&gt;second&lt;/option&gt;
&lt;/select&gt;
...
&lt;/table&gt;
&lt;div&gt;
   &lt;input id="Add-btn" class="button" type="button" value="Add" /&gt;
   &lt;span&gt;&lt;/span&gt;
&lt;/div&gt;
</code></pre>
