Cloning and update attributes

My first question is here, but stackoverflow was a very valuable resource for me last year.

I am creating an extended form. I need the user to be able to add subgroups. I am using jquery (1.5.1 - suppose I have to update) to clone an object. My problem is that I also need to update the attributes.

I was wondering if there is a way to do this that I cannot find or if I have to write it myself. It seems to be an easy task to do attribute counting and add one.

I presented a short example of some code.

<form class="clause">
  <input type="radio" id="radio-1" name="radio" checked="checked" />
    <label for="radio-1">And</label>
  <input type="radio" id="radio-2" name="radio" />
    <label for="radio-2">Or</label>
  <input type="radio" id="radio-3" name="radio" />
    <label for="radio-3">Not</label>
 <button class="ag">Add SubGroup</button>
</form>


<!-- yes, this is in an external file -->
<script type="text/javascript">

$(function() {
  $('.ag').click(function() {
$('.clause').clone(true).insertAfter($('.clause:last'));
 });
</script>

It duplicates, quite nicely, the form and inserts a copy after itself.

        <label for="radio-1">And</label>
      <input type="radio" id="radio-2" name="radio" />
        <label for="radio-2">Or</label>
      <input type="radio" id="radio-3" name="radio" />
        <label for="radio-3">Not</label>
      <button class="ag">Add SubGroup</button>
   </form>
   <form class="clause">
      <input type="radio" id="radio-4" name="radio" checked="checked" />
        <label for="radio-4">And</label>
      <input type="radio" id="radio-5" name="radio" />
        <label for="radio-5">Or</label>
      <input type="radio" id="radio-6" name="radio" />
        <label for="radio-6">Not</label>
      <button class="ag">Add SubGroup</button>
   </form>

   <!-- yes, this is in an external file -->
   <script type="text/javascript">
    $(function() {
      $('.ag').click(function() {
    $('.clause:last').clone(true).insertAfter($('.clause:last'));
     });
    </script>

$('.ag').click(function() {
  // I would advise using :last so you don't exponentially grow your form
  var clone = $('.clause:last').clone(true);

  // now find all the radios and reset them
  $('input[type=radio]',clone).removeAttr('checked');

  // now add it
  clone.insertAfter($('.clause:last'));
});
