I'm having trouble solving this one

In index.html, create a button that updates the $scope.name property to 'Treehouse' when clicked.

index.html 
<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <title>Angular.js</title>
  <script src="js/angular.js"></script>
  <script src="app.js"></script>
</head>
<body ng-controller="myController">

  <p>Hello {{name}}</p>
  <!-- YOUR CODE HERE -->

</body>
</html>

You need to use the built in ng-click directive to set {{name}} equal to 'Treehouse' when the button is clicked.

<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <title>Angular.js</title>
  <script src="js/angular.js"></script>
  <script src="app.js"></script>
</head>
<body ng-controller="myController">

  <p>Hello {{name}}</p>
  <!-- YOUR CODE HERE -->
  <button ng-click="name = 'Treehouse'">Click Here</button>
</body>
</html>

If it were something like 

<body ng-controller="myController">

  <p>Hello {{person.name}}</p>
  <!-- YOUR CODE HERE -->
</body>

Then you'd just make sure to scope the button accordingly

<body ng-controller="myController">

  <p>Hello {{person.name}}</p>
  <!-- YOUR CODE HERE -->
  <button ng-click="person.name = 'Treehouse'">Click Here</button>
</body>
