Answer 1

You have 2 unnamed ng-app directives in your html.
Lose the one in your div.

Update
Let's try a different approach.
Define a module in your js file and assign the ng-appdirective to it. After that, define the controller like an ng component, not as a simple function:

and the js part:

angular.module('myAppName', [])
    .controller('FirstCtrl', function($scope) {
         $scope.data = {message: 'Hello'};
    });

Here's an online demo that is doing just that : http://jsfiddle.net/FssbL/1/
