html - Jquery click event not working after append method

Question

So I have this button which adds a new row to the table, however my problem is that it does not listen to the .new_participant_form click event anymore after the append method has taken place.

http://jsfiddle.net/cTEFG/

Click Add New Entry then click on the Form name.

$('#add_new_participant').click(function() {


    var first_name = $('#f_name_participant').val();
    var last_name = $('#l_name_participant').val();
    var role = $('#new_participant_role option:selected').text();
    var email = $('#email_participant').val();


    $('#registered_participants').append('<tr><td><a href="#" class="new_participant_form">Participant Registration</a></td><td>'+first_name+ ' '+last_name+'</td><td>'+role+'</td><td>0% done</td></tr>');

    });

    $('.new_participant_form').click(function() {

        var $td = $(this).closest('tr').children('td');

        var part_name = $td.eq(1).text();
        alert(part_name);

    });
});

HTML

<table id="registered_participants" class="tablesorter">

<thead>
<tr> 
<th>Form</th>
<th>Name</th>
<th>Role</th>
<th>Progress </th>


</tr> 
</thead>


<tbody>
<tr> 
<td><a href="#" class="new_participant_form">Participant Registration</a></td>
<td>Smith Johnson</td>
<td>Parent</td>
<td>60% done</td>


</tr> 
</tbody>

</table>

<button id="add_new_participant"></span>Add New Entry</button> 

Answer 1

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.
