recursion issue with preventDefault on form submit with jquery

Question

I have a form that takes some inputs, everything there is peachy. From this form I want to take a input value and assign it to a hidden value via jquery. To do this I had written the following:

<script type="text/javascript">
    jQuery(document).ready(function() {
        function preventDefault(e){
            e.preventDefault();
        }

        jQuery('#rsvp-form').bind('submit', preventDefault);
        jQuery('#rsvp-form').submit(function(e) {
            var emailvalue = jQuery('#personemail\\[0\\]').val();
            jQuery('#person_email').val(emailvalue);
            alert(jQuery("#person_email").val());
            jQuery('#rsvp-form').unbind('submit', preventDefault);
            jQuery(this).trigger('submit');
        });
    });
</script>

I'm binding .preventDefault to the submit just fine along with changing my value without issue. The problem is submitting the form after changing the value. No matter what I've tried it ends in an endless loop. If I remove the trigger or a .submit() or something along those lines and just leave it with the unbind, nothing happens. Kind of stumped at this point.
