angular can't find a controller when using require.js

so in this example:

<div ng-controller="myController">
    {{name}}
</div>

function myController($scope){
   $scope.name = "Jack Robinson";
}

it works. but how do I use it with require.js? Next snippet doesn't work

define(function(){
   return function myController($scope){
      $scope.name = "Jack Robinson";
    }
})

it says: 'myController' is not a function, got undefined
