Solution

  • The error is that you have not attached a scope variable with dish. Instead of using this.dish, make it $scope.dish. I have updated your controller function below which should work.

    app.controller('dishDetailController', function($scope) {
                    var dish = {
                        name:'Uthapizza',
                        image: 'images/uthapizza.png',
                        category: 'mains',
                        label:'Hot',
                        price:'4.99',
                        description:'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',
