AngularJS code for 'controller' does not kick in

Question

I am new to AngularJS and do have the task of enhancing existing code.

Simplified, the following is in the html-file:

<div class="popup-list" ng-controller="NumberCtrl">
  First number: <input type="number" ng-init="$scope.firstNum">
</div>

And this I want to have referred in a JavaScript-file:

angular.module('app').controller('NumberCtrl', function ($scope)
{
  $scope.firstNum = 100
});

However the modal window popups up providing the input field, but no value = 100 is pre-defined.

What is going wrong here?

you should use ng-model instead of ng-init which provides you two way binding feature.. — Pankaj Parkar

you don't need to tag scope in view .

whatever you use on view it'll get from $scope.

use ng-model in input control in order to bind data.

Like this

First number: <input type="number" ng-model="firstNum">

You are may be getting module without setting it.

Try like this

angular.module('app',[]).controller

To get a module

angular.module('app')

To set a module

angular.module('app',[])

Also, you have to initialize the module like: angular.module('app', []);. Before using it (note the empty array [] that tells angular that you have 0 dependencies and you are initializing a new module).
