The method doSomething() needs the NEW entered quantity to, obviously, do something
The problem here is when I use the browser arrows for type number (up and down little arrows for increment and decrement the value), because they do not trigger the (change) event. They do trigger the (input) event, but input event gets the old quantity, not the new one entered.
Yes, @ajohan, you are right, but it that way the event is not fired until the ion-input looses the focus, it is not the expected behaviour too. I think the expected behaviour should be (or at least MY expected behaviour) that the model updated each time I press the arrow, and doSomething() is triggered with the NEW value.
