[jQuery] Script Wouldn't Work After Content Reloaded

[SHiDi]

Hi all.

I've tried to reload a content using jQuery.post. However, it seems
that once the content is reloaded, the script didn't work the way it
supposed to.

My jQuery script is:

    $(".click").click(function() {
        alert('Hello World');

        $.post('actions.php',
         {},
         function(data) {
             $("#new").html(data);
         });
    });

Content for actions.php:

echo '<a href="#" class="click">Click Me Again</a>';

As for the HTML:

<div id="new">
  <a href="#" class="click">Click Me</a>
</div>

On first click, the script will work. But once the content reloaded,
it's no longer work. Any idea why?

Thanks in advanced :)
