Make your JQuery call more robust by adding success and error callbacks like this:

 $('#ChangePermission').click(function() {
     $.ajax({
         url: 'change_permission.php',
         type: 'POST',
         data: {
             'user': document.GetElementById("user").value,
             'perm': document.GetElementById("perm").value
         },
         success: function(result) { //we got the response
             alert('Successfully called');
         },
         error: function(jqxhr, status, exception) {
             alert('Exception:', exception);
         }
     })
 })
