I have trouble to test something simple like this

```auto
<input value.bind="message">

```

Aurelia doc says it will update model on “change” and “input” event. [https://aurelia.io/docs/binding/binding-behaviors#updatetrigger](https://aurelia.io/docs/binding/binding-behaviors#updatetrigger)

I try to use jQuery to mutate the input, then manually trigger a “change” event. But my model “message” still doesn’t update.

```auto
jQuery('input').val('test').trigger('change');

```

Here is a gistrun to demonstrate my problem. Did I do something wrongly?

I have a feeling that jquery does some internal magic with events which Aurelia can’t detect.

I changed the gist to a functional one by using jquery’s `get` to return the actual html element and then triggering the event in the native vanilla js way

You can easily replace all of that jquery code though. Check the gist again, removed all the jquery “crap”. 🙂
