dhtmlxCalendar and input - some changes had occurred

I use dhtmlxCalendar.

My task:
I have any number of INPUT tags with Calendar.
I choose date in ANY INPUT → this date set in ALL INPUT

It works if I print date myself.
But it doesn’t work if I choose date in dhtmlxCalendar

function doOnLoad() {
    myCalendar = new dhtmlXCalendarObject(["calendar1","calendar2","calendar3"]);
	myCalendar.setDate(new Date());
	myCalendar.attachEvent("onClick", function() {
		var element = document.getElementById('calendar1');
		if( window.KeyEvent ) // Для FF
			var o = document.createEvent('KeyEvents');
			o.initKeyEvent( 'input', true, true, window, false, false, false, false, 13, 0 );
		else // Для остальных браузеров
			var o = document.createEvent('UIEvents');
			o.initUIEvent( 'input', true, true, window, 1 );
		o.keyCode = 13; // Указываем дополнительный параметр, так как initUIEvent его не принимает
 <body onload="doOnLoad();">
<input type="text" id="calendar1" ng-model='value1' />
<input type="text" id="calendar2" ng-model='value1' />
<input type="text" id="calendar3" ng-model='value1' />



this thing do the trick

try to set custom ng-model=‘value1’ to inputs, i.e. value1, value2, value3
