International plug-ins doesn't work with datatable as input (editor)

[fbognini]

Hi,
I've found a problem with internationalization plug-ins.
If you use a datatable as input and you specify config.language.url parameter, datatable doesn't show.

For example (using resource json file provided in examples):

config: {
      language: {
          url: "../resources/fr.json"
      },
  }

I've just tried with nested.html and select.html and it doesn't work. I think it's a bug.
