Codeigniter with Ajax

[eluser]Joshi[/eluser]
i have used onchange event in select method but it doesn’t get printed in the post.
<select name="accountNoForACH" id="accountNoForACH">
&lt;?php if($bnkDetails)
{

foreach($bnkDetails as $in){?&gt;
<option value="&lt;?php echo decrypt($in->accountNo) ?&gt;">&lt;?php echo decrypt($in->accountNo) ?&gt;</option>
&lt;?}
}?&gt;
</select>
