Firing $watch event manually in angularjs

Firing $watch event manually in angularjs

We have few options:

1. Use $scope.$apply() to run the digest loop which call all of the watch expressions.
2. Put you inner watch code inside a function and call it manually.
3. Change messages.

Explanation for second one:

var watchFunc = function(){
    // the code
}

$scope.$watch('message',watchFunc);

watchFunc();
