You can dynamically add event handlers using JavaScript. You can add a script that, once the page is loaded, will find all checkboxes you want and add the handlers there. In jQuery, you can write something like this:
$(document).ready(function() {
$(".my_form input[type=checkbox]").change(function() {
//Some code here
});
});
Be careful, I have not tested the code above! But should be enough to get you started.
