For observing inputs, you might consider using reactive forms and subscribing to the valueChanges observable on the form or formControl in question.

Ohh true, I did not consider this approach, I didn't like to have to pass in the element reference to fromEvent, I don't usually like manipulating elements directly so the reactive form could be a really nice solution.

Thanks for the info!
