To be able to access a variable from the template, this variable must be on the $scope. If you only expose it on the controller itself (i.e. using this.dish = ...), then the controller itself must be on the $scope, using

<div ng-controller="DishDetailController as ctrl">
  ...
  {{ ctrl.dish.name }}
</div>

Change the line:

this.dish = dish;

for:

$scope.dish = dish;

Also, just after your module definition add:

$scope.dish = {};

Just add to it. Should add $scope in controller declaration as well. app.controller('DishDetailController', function($scope)

You forgot to add controller as syntax in the ng-controller directive.

Working Demo :

angular.module('confusionApp', [])

.controller('DishDetailController', function () {
   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.',
