Jquery and dynamic content

Hello,
I am currently trying to learn javascript by way of the missing manual: javascript.  I was starting to get a hand on javascript until I started using jquery.  My problem is that I can not figure out how to access dynamic content with jquery.  Been looking on the net for hours but was unable to come up with a solution.

The code below applys the greybox function to all  ('inpage a').  The problem I am having is not with the initial page, but when I dynamically load content with Ajax.  I guess i need a way to recall the function and reapply it to the dynamically loaded content.  

I thought I was on to something with the .live  but was unable to successfully implement it,  thanks in advance.

<script type="text/javascript">
$(document).ready(function() {
  var gbOptions = {
    gbWidth: 700,
    gbHeight: 550
  };
	$('.inpage a').greybox(gbOptions);
});
</script>
