your app has multiple issues, but the one that stands out is that you are defining your dish_cmnt as a simple var, which will never be accessible to the HTML. It either needs to be a property of $scope, or it needs to be a property of your controller. You might want to study some more angular examples. — Claies

And even when you added ngApp, it will still won't work because you're not declaring your controller using ng-controller="dishDetailController as vm" (And then - {{vm.dish_cmnt.name}}, etc..) — Alon Eitan

also, this.dish = dish would throw an error, since dish isn't defined anywhere. — Claies

Firstly, you were missing ng-app="confusionApp" so I added that.

Next, your template didn't have a reference to dishDetailController so did that using ng-controller="dishDetailController as ctrl" and using ctrl.dish_cmnt instead of direct dish_cmnt.

Next, this.dish = dish was throwing error since dish was undefined. Changed that to this.dish_cmnt = dish_cmnt since we needed reference to dish_cmnt anyway.

That fixed it.

Here's your working code snippet.

var app = angular.module('confusionApp', []);

app.controller('dishDetailController', function() {

  var dish_cmnt = {
    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.',

I tried this but it does not show the content but {{ctrl..dish_cmnt.name}} and all others like this
@GiteshSawariya what ever you have after ctrl should be defined in your controller. So here, if you want to show ctrl.name, you gotta have this.name = "gitesh" in your controller somewhere
@GiteshSawariya there might be some other issue then. you can maybe create a fiddle/plunker to reproduce the issue and share it here?
