Load() issue and script getting disabled?

Load() issue and script getting disabled?

I followed a simple example on the jquery site where I load a html page inside a div. The page does load inside the div correctly however what i noticed is that the page that loads inside the div, its jquery scripts don't work. .

when i call the page by its own the jquery scriptes work:

code in js file:
/* Loads the default contact page inside the content div using the jquery ajax api  */
$(document).ready(function () {
  $("#showcontactusform").click(function(event){
      $('#contentdetails').load('/contact/contactform1.html');
  });
});


Am I missing something?
