Struggling with linking my Angular Controller with my View and experiencing difficulty establishing a connection

I'm encountering an issue while attempting to link a controller to my view. The error I keep receiving is as follows:

Error: ng:areq Bad Argument Argument 'TestAppCtrl' isn't a function, received undefined

Here's the content of my view:

<!DOCTYPE html>
<html ng-app lang="en">
<!-- Head section here -->
  <body ng-app="app">
    <div class="container">

        <!-- Resume section -->
            <div ng-controller="TestAppCtrl" id="TestAppCtrl">
            {{data}}
            </div>   

    </div>
  </body>
</html>

This is the related controller code: // Generated by CoffeeScript 1.9.3 var app;

app = angular.module('app', []);

console.log("hello world");

app.controller('TestAppCtrl', ['$scope', function($scope) {
  $scope.data = [1, 2, 3, 4, 5];
}]);

Although the correct controller is being detected (as evidenced by the console log), the data from the controller isn't binding in the view and instead appears as {{data}}. Any suggestions on resolving this issue would be greatly appreciated. Thank you.

You seem to have a duplicate ng-app declaration

<!DOCTYPE html>
<html ng-app lang="en">
...
</head>
<body ng-app="app">

When using Angular, remember that it will only recognize the first ng-app on the page. It looks like your initialization code is pointing to the second ng-app declaration.

app = angular.module('app', []);
