hidden input fields don't trigger the change() event.
For users who may just want to observe changes to the hidden input value and respond to it e.g.
```js
$("input[type=hidden]").bind("change", function() {
console.log($(this).val());
});
```
This fix force-triggers the change() event and also only sets the value (and therefore the change) when the input value has changed.
