    model() { 
        this.init(); 
        return this.fruits; 
    } 
    setupController(controller, model) { 
        super.setupController(controller, model); 
        controller.set('fruits', this.fruits); 
        controller.set('item1', this.item1); 
        controller.set('item2', this.item2); 
        controller.set('item3', this.item3); 
    } 
}
