Deep watch tien-clndr-events

[PhilHuot]

Having this set up (no $watch needed in the controller) we need to deep watch the tien-clndr-events attribute so that the changes in the service are reflected in the controller.

function myController(myEventService){
    this.events = myEventService.events;
    myEventService.getEvents();
}

function myEventService() {
    var self = this;
    self.events = [];
    this.getEvents = function() {
        return $http.get('/api/events').then(events) {
            angular.copy(events, self.events)
        }
    }
}
