AngularJS: How to pass data from view to controller in angularjs

Question

I'm developing an application which adds/edits/removes contacts. Here is how my adding contact view template looks like:

<input placeholder="name" ng-model="contact.name" type="text">
<input placeholder="number" ng-model="contact.number" type="text">
<a href="#/"><button>Add</button></a>

And here is my controllers file, the controller used for adding is the last one:

var myApp = angular.module('myApp', ['ngRoute']).config(function ($routeProvider) {
    $routeProvider.when('/contact/:index', {
        templateUrl: 'partials/edit.html',
        controller: 'Edit'
    }).when('/', {
        templateUrl: 'partials/contacts.html'
    }).when('/add', {
        templateUrl: 'partials/add.html',
        controller: 'Add'
    })
    .otherwise({ redirectTo: '/' });
}).controller('Contacts',  ['$scope',function($scope){
    $scope.contacts = [
    {name:'Hazem', number:'01091703638'},
    {name:'Taha', number:'01095036355'},
    {name:'Adora', number:'01009852281'},
    {name:'Esmail', number:'0109846328'}
    ];
}]).controller('Edit', ['$scope','$routeParams',function($scope,$routeParams){
    $scope.contact = $scope.contacts[$routeParams.index];
    $scope.index = $routeParams.index;
}]).controller('Add', ['$scope', function($scope){
    $scope.contacts.push({name: contact.name, number: contact.number});
}]);

I've got an error in the chrome inspector says: ReferenceError: contactname is not defined

Please see below

use <button ng-click="Add()">Add</button> instaed of <a> tag

var myApp = angular.module('myApp', [])
.controller('Add', ['$scope', function($scope){
  $scope.contacts = [];
  $scope.Add = function() {
    $scope.contacts.push({name: $scope.contactname, number: $scope.contactnumber});
    }
}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="Add">
<input placeholder="name" ng-model="contactname" type="text">
<input placeholder="number" ng-model="contactnumber" type="text">
<button ng-click="Add()">Add</button>
 
    <ul>
    <li ng-repeat="con in contacts">{{con.name}} {{con.number}}</li>
    </ul>
    
    </div>
  </div>

In your Add controller change

.controller('Add', ['$scope', function($scope){
    $scope.contacts.push({name: contactname, number: contactnumber});
}]);

.controller('Add', ['$scope', function($scope){
    $scope.contacts.push({name: $scope.contactname, number: $scope.contactnumber});
}]);
