Modelpopup not showing in ie9
<p>Help me I used the <code>.show()</code> method to show a modal popup. In ie9 this is not working:</p>

<pre class="lang-xml prettyprint-override"><code>&lt;AjaxControlToolkit:ModalPopupExtender 
    ID="mpeChangePassword" 
    runat="server" 
    TargetControlID="lbtnChangePassword"
    CancelControlID="lbtnCancel" 
    PopupControlID="divChangePassword" 
    BackgroundCssClass="modalBackground"
    RepositionMode="RepositionOnWindowResizeAndScroll"&gt;
&lt;/AjaxControlToolkit:ModalPopupExtender&gt;
&lt;asp:LinkButton ID="lbtnChangePassword" runat="server" Text=""&gt;&lt;/asp:LinkButton&gt;
</code></pre>

<p>javascript:</p>

<pre><code>function OnPasswordChangeClick()  {
    $("#&lt;%= PopupMessageLabel.ClientID %&gt;").text('');
    $find("#&lt;%=mpeChangePassword.ClientID %&gt;").show();
}
</code></pre>
