You could define your actions for those focus-in, focus-out, key-press, insert-new-line, enter view events.
{{textarea value=item.text focus-out="validate"}}
This documentation is missing.
Question
How can I make this textarea trigger an action when it loses focus?
{{textarea value=item.text}}
I'm guessing that there is a way to do it with custom views but I'm just not able to make sense of it yet.
