jQuery trigger onChange

I can't imagine the problem lies with .change() perhaps somewhere else in your code, I have just tested and the event will get fired if I copy and paste, or if I type some new text (with both normal and onscreen keyboard).

The only time it didn't seem to trigger was when I dragged some text clipping from the desktop to the input box but this was to do with it being highlighted and sure enough when the input box lost focus the event triggered (I can't think of any other use cases)

You can do something like below using the blur() or focusout() event which essentially I believe is the change event

function foo(e) {
    alert(e.type + ' triggered');
}

$('input').blur(function(e) {
    $t = $(this);
    if ($t.data('oVal') != $t.val()) {
        $t.data('oVal', $t.val());
        foo(e);
    }
})
