title: How to unbind $on in Angular?
body: <p>I have a code that use <code>$scope.$on</code> one time on init and then in a function, so the code is executed multiple times. How can I unbind if first before I bind it again. I've try <code>$scope.$off</code> but there's not such function, <a href="https://docs.angularjs.org/api" rel="nofollow noreferrer">https://docs.angularjs.org/api</a> say nothing about <code>$on</code>. I'm using angular 1.0.6.</p>
