Problem if CI > default CO

[AndreyBragin]

Hello thx for ur grate work! I have the problem) When i select checkin date and it more than checkout date, input with checkout date cleared. I was tried event "onChangeCI" and tried update with method 'updateCO' this give me error: Uncaught TypeError: Cannot set property 'innerHTML' of undefined. May be i'm doing something wrong ?) Can u help me?

This my code: `let datePicker = $('.t-datepicker');

let today = new Date();
let tomorrow = new Date();

tomorrow.setDate(today.getDate() + 1);
let getCheckIn = datePicker.find('input[name=checkin]').attr('data-value');
let getCheckOut = datePicker.find('input[name=checkout]').attr('data-value');

datePicker.tDatePicker({
startDate: today,
limitDateRanges: 31,
titleToday: 'Сегодня',
titleDays: ['Пн', 'Вт', 'Ср', 'Чт', 'Пт', 'Сб', 'Вс'],
titleMonths: ['Январь', 'Февраль', 'Март', 'Апрель', 'Май', 'Июнь', 'Июль', 'Август', 'Сентябрь', 'Октябрь', 'Ноябрь', 'Декабрь'],
iconArrowTop: false,
iconDate: '',
titleDateRange: '',
titleDateRanges: '',
titleCheckIn: '',
titleCheckOut: '',
dateCheckIn: getCheckIn ? getCheckIn : today,
dateCheckOut: getCheckOut ? getCheckOut : tomorrow,

}).on('onChangeCI', function (e, changeDateCI) {
datePicker.tDatePicker('updateCO', '2019-01-31')
});`
