issue with <cfform> and <form>

Hi everybody I'm having an issue with <cfform>, <form> on Firefox, I have a .cfm page where I´m using AJAX to show another .cfm into a <div> tag when the user click a button, my issue is firefox doesn´t show the Mynewpage's <cfform> or <form> but Internet Explorer does

on IE show the cfform without issues, but FF shows just the things before <cfform>

my first page code:

<table>

     <tr>

          <td>

               <input type="button" name="button1" onclick="javascript: ajax = new Ajax.Updater('MyDiv','Mynewpage.cfm?a=b', {method:'get'});">

          </td>

     </tr>

</table>

<div id="MyDiv"></div>

Mynewpage code:

<cfoutput>Hi type your name<cfoutput>

<cfform>

<table>

     <tr>

          <td>

               Name:

          </td>

          <td>

               <cfinput name="name1">

          </td>

     </tr>

</table>

</cfform>

somebody knows how can I resolve it???
