how do i access the eliments of a page that has been .load() into a new page

Hello everyone

i am new to jquery but love it already ( i am a php programmer).

i have just use the .load() function to load content from another page to a new page. i am able to load the contents.
However, i now wish to accesssome elements of the newly loaded content but i am not able to do this.

  1.   $(document).ready(function() {
  2.   $('#signin a').click(function() {
  3.      var url=$(this).attr('href');
  4.      $('#loginpostion').load(url + ' #loginform');
  5.      return false;
  6.  
  7.  
  8.     $('#closebox a').click(function() {
  9.         
  10.          alert('itworks');
  11.     //     $('#loginpostion').removeClass()
  12.         
  13.      return false;
  14.         
  15.         
  16.   }); //end click 
i wish to access the following A tag from the newly loaded page: #closebox a

Is there anything that i need to do to let Jquery know that the "newly loaded content" will now form part of the DOM of the current page

warm regards

Andreea
