I have just created a very simple app. 
It only contains one function which is used in ng-click. 
Somehow, ng-click is not firing. 
Can anyone take a look for me?

```
var app = angular.module('myApp');

app.controller('createController', ['$scope', function($scope){
    $scope.submitProject = function(){
    alert('wahaha');
};

}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!DOCTYPE html>
<html ng-app="myApp">

    <link rel="stylesheet" href="style.css">
    <script src="script.js"></script>

<body>
    <h1>Hello Plunker!</h1>
    <div class="form-group text-right">
        <button class="btn btn-primary btn-lg" ng-click="submitProject()">Submit</button>
    </div>
</body>
</html>
