问题
For a mockup I need a simple mechanism like
ng-click="alert('Clicked')"
but the code above is not working, can someone help me? I don't want to touch the Controller..

As far as I know, ng-click works only within your $scope. So you would only be able to call functions, defined in your $scope itself. To use alert, you may try accessing the window element, just by using window.alert('Clicked').
EIDT: Thanks to Ibrahim. I forgot. You shouldn't be able to use window.alert, as far as you won't define:
$scope.alert = window.alert;
In this case, using alert('Clicked') in your ng-clicked directive should work. But at the end, this method would not solve your problem of not touching your controller.

Refer to previous answer, ng-click = "alert('Hello World!')" will work only if $scope points to window.alert i.e
$scope.alert = window.alert;
But even it creates eval problem so correct syntax must be:
HTML
<div ng-click = "alert('Hello World!')">Click me</div>
Controller
$scope.alert = function(arg){
alert(arg);
}

As Neeraj mentioned, the accepted answer does not work. Add something like this to your controller to avoid an Illegal Invocation error:
$scope.alert = alert.bind(window);
