Telegram bot: How to get chosen inline result

I'm sending InlineQueryResultArticle to clients and i'm wondering how to get chosen result and it's data (like result_id,...).

here is the code to send results:

token = 'Bot token'
bot = telegram.Bot(token)
updater = Updater(token)
dispatcher = updater.dispatcher

def get_inline_results(bot, update):
    query = update.inline_query.query
    results = list()

    results.append(InlineQueryResultArticle(id='1000',
                                            title="Book 1",
                                            description='Description of this book, author ...',
                                            thumb_url='https://fakeimg.pl/100/?text=book%201',
                                            input_message_content=InputTextMessageContent(
                                                'chosen book:')))

    results.append(InlineQueryResultArticle(id='1001',
                                            title="Book 2",
                                            description='Description of the book, author...',
                                            thumb_url='https://fakeimg.pl/300/?text=book%202',
                                            input_message_content=InputTextMessageContent(
                                                'chosen book:')
                                            ))

    update.inline_query.answer(results)


inline_query_handler = InlineQueryHandler(get_inline_results)
dispatcher.add_handler(inline_query_handler)

I'm looking for a method like on_inline_chosen(data) to get id of the chosen item. (1000 or 1001 for snippet above) and then send the appropriate response to user.
