Input text in draft.js

I'm doing automation test and I need to input text in a text field, but the problem is there is no 'input' to do this.

This one won't work:

document.querySelector([class*=modal-dialog] [class*=AddCitation_] [class*='DraftEditorPlaceholder']).value='Hello World'

Does any one know how to input text in draft.js?
