Menu
I have a jsfiddle here - http://jsfiddle.net/FTHVJ/
And demo here - http://ttmt.org.uk/select
I know this looks a little crazy but it's cloest I could get to the actual code.
I have an on 'change' event handler on a select menu #menu_One
This then adds a new select menu #menu_Two that is saved in jquery as a variable.
I'm then trying to add an on 'change' event handler to this added select menu.
The on 'change' event doesn't work on thw added select menu.

For dynamically created elements, you need to use the .on function:
$('#new_select').on('change', '#menu_Two', function(){
alert('here');
});
Event listeners can only be attached to elements that are in the DOM, not elements that don't exist at the time.

Try:
$(document).on('change', '#menu_Two', function(){
alert('here');
});

You shouldn't add the event handler until you've added the DOM node:
$(function(){
var select_two = "<select id='menu_Two'>";
select_two += "<option>Menu Two 1</option>";
select_two += "<option>Menu Two 2</option>";
select_two += "<option>Menu Two 3</option>";
select_two += "<option>Menu Two 4</option>";
select_two += "</select>";
$('#menu_One').on('change', function(){
$('#new_select').append(select_two);
$('#menu_Two').on('change', function(){
alert('here');
})
});
});
