Div Inner HTML Only Changes The First Time?

I am having this events calendar :

Code: [URL]

Clicking on prev, next should display the calendar of the current month and highlights the events (if any).

I have written the following Javascript:

calendar.php: retrieves the html of the calendar of the month

Code JavaScript:
<script type="text/javascript">
$(function(){
$(".mylinks").click(function(){

[Code]....

The script works perfectly well on clicking the prev/next links the first time. But doesn't seem to call the script the second time, as if the script is longer aware of the presence of the newly loaded inner html..
