Problem submiting value, form_for, link-to-remote, javascrip

This is my form. It creates a comment in the database but won't pass the
'body' value. I think the problem is passing the variable to javascript.
Can anyone help?

<% form_for :comment, :url=>story_comments_path(@story), :name =>
'form' do |form| %>
  <fieldset>
       <label for="login">Comment:</label>
       <div id="body"><%= form.text_field :body %></div>
       <%= link_to_remote('comment',{ :url =>
                                         {:controller => 'comments' ,
                                          :action => 'create',
                                          :story_id => @story.id,
                                          :method => 'get',
                                          :with =>
'serialize_fields()' }}) %>
    </fieldset>
  <% end %>

This is the javascript.

<script>
function serialize_fields(){
  var fields = new Array();
  fields.push(Form.Element.serialize('document.form.body'));
  return fields.join('&');
}
</script>

Your serialize_form method looks borked. You could use the
remote_form_for method alternatively, prototype already provides a
serialise method for forms - $('id_of_the_form').serialize() will
serialise all then inputs in the form

I tried this too

:with=>"'body' + $F('body')"

That doesn't work either. How can I pass this parameter?
