Targeting Sharepoint form drop down
<p>I have a newform.aspx created through SPD. Its already contains a drop down list.</p>

<pre><code>&lt;SharePoint:FormField runat="server" id="ff4{$Pos}" ControlMode="New" FieldName="Enquiry_x0020_Type" __designer:bind="{ddwrt:DataBind('i',concat('ff4',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Enquiry_x0020_Type')}"/&gt;
</code></pre>

<p></p>

<p>I have some javascript that i want to invoke when the drop down list changes.</p>

<pre><code>$(document).ready(function() {

$("#ff4{$Pos}").change(function() {
    alert("drop down change");     
    });});
</code></pre>

<p>But nothing happens, I tried adding my own drop down and using its ID and this works fine, but I cannot correctly target the existing SP form drop down.</p>
