[jQuery] How to bind validation to new loaded form?

[[EMAIL PROTECTED]]

Hi all,
i have tried to transform a bind example to my situation, but i can't
get it working.
Via my menu, i load a form which i want to validate.
( with Validation plugin from 
http://bassistance.de/jquery-plugins/jquery-plugin-validation/

Loading the form into my content div works fine, validation fails.

maybe someone can give me a hint how to solve this?
thanks in advance....

See my (small) code below:

loaded javascript:
 <!-- jQuery en plugins -->
 <script src="JS/jquery-1.2.6.min.js" type="text/javascript"></script>
 <script src="JS/jquery.validate.min.js" type="text/javascript"></
script>



$(document).ready(function() {

   // Menu

   $('.sub li a').click(function(){
            // test alert
                  //alert("clicked on sub item..");

      var toLoad = $(this).attr('href');
                  // test alert
                  //alert("content to load: " + toLoad); got this alert
      $('#content').hide('normal',loadContent);
      $('#load').remove();
      $('#wrapper').append('<span id="load">LOADING...</span>');
      $('#load').fadeIn('normal');
      function loadContent() {
           $('#content').load(toLoad,'',showNewContent())
      }
      function showNewContent() {
           $('#content').show('normal',hideLoader());
      }
      function hideLoader() {
           $('#load').fadeOut('normal');
      }
      return false;
   });

   // nieuwe speler...laadt aanmeld formulier

         $('#nieuwespeler').click(function(){
            //alert("Nieuwe speler! howra"); Got this alert
                        var toLoad = 'forms/registreren.php';
      $('#content').hide('slow',loadContent); // fast, slow, normal or
milliseconden??
      $('#load').remove();
      $('#content').append('<span id="load">LOADING...</span>');
      $('#load').fadeIn('slow');
      function loadContent() {
           $('#content').load(toLoad,'',showNewContent())
      }
      function showNewContent() {
           $('#content').show('slow',hideLoader(),function(){
                                    $("#registratieform").validate();// rebind 
valideer aanmeld
formulier ???
                                 });// fast, slow, normal or milliseconden??
      }

      function hideLoader() {
           $('#load').fadeOut('slow');
      }

            return false;
   });
});

And this is my form:

<div id="register">
<fieldset>
<legend>Nieuwe speler aanmaken</legend>

<form id="registratieform" method="get" action="">


   <input type="hidden" name="TMS_ToDo" value="NewUser" ><!--

naar standaard instelling -->

                <p>
                        <label for="agree">Ik ga accoord met 
gebruikersvoorwaarden</label>
                        <input type="checkbox" id="agree" name="agree" />
                        <a href="#">Lees hier de gebruikersvoorwaarden!</a><!--

                </p>
        <button id="registreren" type="submit"
