Пришлось реализовать на hooks

export const EditNotePopup = (props) => {

	const { editNote, idNote, textEditedNote } = props

  const [editorState, setEditorState] = 
  useState(EditorState.createEmpty())

  const getContentFromHTML = (stringHTML) => {
    const blocksFromHTML = convertFromHTML(stringHTML);
    const content = ContentState.createFromBlockArray(
      blocksFromHTML.contentBlocks
    );
    return content
  }

  useEffect (() => {
  	if(textEditedNote !==""){
					setEditorState(
		      	EditorState.createWithContent(
		      		getContentFromHTML(textEditedNote)
		    		)
		      );
		  }
	}, [textEditedNote]);

	// for export text note toHTML
	const toHTML = (raw) =>
	  raw ? convertToHTML(exporterConfig)(convertFromRaw(raw)) : ""

	return (
		<div
			id="modal-editNote"
			className="modal fade"
			tabIndex={-1}

                  // приводим текст записи к html-string
                  const editedTextNote = 
                    toHTML(
                      serialiseEditorStateToRaw(
                      	editorState
                    	)
                    )
                  // отправляем editedNote в store
                  editNote(idNote, editedTextNote);
                  // очищаем поле редактора
                  setEditorState(EditorState.createEmpty());
								}}
								type="button"

								SAVE
