<!DOCTYPE html>
<script src="//"></script>
<body ng-app >
<div ng-controller="simpleController">
<strong>First name:</strong> {{firstName}}<br />
<strong>Last name:</strong> {{lastName}}</span><br />
<strong>Full name:</strong> {{getFullName()}}<br />
<label>Set First name: <input type="text" ng-model="firstName"/></label><br />
<label>Set Last name: <input type="text" ng-model="lastName"/></label>
var simpleController = function ($scope)
  // Initialize the model variables
  $scope.firstName = "Max";
  $scope.lastName = "Joe";
  // Define utility functions
  $scope.getFullName = function ()
return $scope.firstName + " " + $scope.lastName;
