Angular.js How to Inject $scope into directive() for $scope.on()?

Question

for the directive I wrote, how do I get $scope in there so I can do $scope.$on()? I could inject $rootScope, but I want to use $scope to catch the broadcast.

angular.module('monitorApp')
.run(function($rootScope, $interval) {
            $interval(function(){
                $rootScope.$broadcast('ONE_SEC');
            }, 1000);
});

angular.module('monitorApp')
.directive("countDown", [ 'sseHandler', function (sseHandler) {
    console.log(sseHandler.broadcastStamp.cpuResult);
    return {
        scope: {
            countFrom: "="
        },
        link: function(scope, $scope){
           scope.countFrom = sseHandler.broadcastStamp.cpuResult;
           $scope.$on('ONE_SEC', function(scope) {
               sseHandler.broadcastStamp.cpuResult--;
           });
        }
    }
}]);

UPDATE: with scope injection, I get error: Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope <- countDownDirective

angular.module('monitorApp')
.directive("countDown", [ 'sseHandler', '$scope', function (sseHandler, $scope) {
    console.log(sseHandler.broadcastStamp.cpuResult);
    return {
        scope: {
            countFrom: "="
        },
        link: function(scope, $scope){
           scope.countFrom = sseHandler.broadcastStamp.cpuResult;
           $scope.$on('ONE_SEC', function(scope, $scope) {
               sseHandler.broadcastStamp.cpuResult--;
           });
        }
    }
}]);

You can just use scope.$on, you don't need to try and inject $scope:

scope.$on('ONE_SEC', function() {
           //do stuff
});
