    Looks to me like your adding the keyup events to the ".submitme" classed elements in the domready, but the firsttextbox isnt yet on the document.

    its added on your #combo's change event so its not getting a keyup event assigned to it.

    When you asynchronously add the combo box (or any element) it does not get the keyup event binding. You have to use .live() like so:

    $(".submitme").live("keyup", function() {
        // stuff
    });
    

    See the jQuery documentation for details on how .live() works.
