angularJS click won't work on my div : We're developing an angularJS site. I can't get the event to work on a div:

<div style="width: 100%; height: 30px;" (click)="alert('Hello!')"></div>

This works when I switch (click) to onclick:

<div style="width: 100%; height: 30px;" onclick="alert('Hello!')"></div>

Why do I get the alert with onclick but not (click)?
