I am new to angularjs. I was trying the following code:
<html>
<body>
    <script src='angular.min.js'> </script>
    <div ng-app>
        <span ng-controller="textController">{{greetMessage}}</span>
    </div>      
    <script>
        function textController($scope) {
            $scope.greetMessage = 'Happy New Year!';
        }
    </script>
</body>
but it prints nothing. What error am I committing?
