Add Handler to all and then call them all

Im trying to add a handler to all checkboxes:-

                $('document').ready(function () {
                    $(':checkbox').change(function () {
                      alert((this).id());
                      });
                });

Select allOpen in new window

And then call them all by:-

 $(':checkbox').are(':checked').trigger('change'); 

Select allOpen in new window

The idea is to add a save to each element, so when the value is saved it executes a ajax request to save the value, but when then are all disabled (done by a button called disableAll) I want it to run the save code on all of the elements (ie run the onChange handler on all the elements).

Something is happening with the trigger as the code takes a few seconds to run, but what I dont know as it doesnt display any alert boxes to me.

Can anyone assist?
