How can I import recaptcha using requirejs. I already tryed several things and nothing works.

I need do that to be able to render it by my own using the method render of reCaptcha once it has been loaded.

```js
require.config({
    paths: {
        'recaptcha': 'http://www.google.com/recaptcha/api'
    }
});

require( ['recaptcha'], function( recaptcha ) {
    // do something with recaptcha
    // recaptcha.render  /// at this point recaptcha is undefined
  console.log(recaptcha);
});
```
