Ember controller: nothing handled the action

I looked through related posts for hours, but could not find the right answer to fix the problem I'm having.

I keep getting the error:

Uncaught Error: Nothing handled the action 'edit'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.

I think that the controller is handling things wrong, or it's bubbling up to a wrong route?

App.EventDetailsController = Ember.ObjectController.extend({
   isEditing: false,

actions: {
    edit: function() {
        this.set('isEditing', true);
    },

    doneEditing: function() {
        this.set('isEditing', false);
    }
    }
});


App = Ember.Application.create();

    App.Router.map(function() {
   // put your routes here
  this.route('events', {path: '/events'});
  this.route('createevent', {path: '/createevent'});
  this.route('eventdetails', {path: ':eventdetails_id'});
});

App.EventsRoute = Ember.Route.extend({
model: function() {
    return events;
}
});

App.EventDetailsRoute = Ember.Route.extend({
model: function(params) {
    return events.findBy('id', params.eventdetails_id);
}
});

Does anyone know why this wouldn't work?
