IE 11 DispatchEvent

Question

We have a datepicker (in JavaScript) that has a section for checking IE 8 and older and other modern browsers.

if(-1 != navigator.userAgent.indexOf("MSIE")){
obj_caller.target.fireEvent("onchange");
}
else {
var evt = document.createEvent("HTMLEvents");
evt.initEvent("change", false, true);
obj_caller.target.dispatchEvent(evt);
}

It's working fine in Chrome, Firefox, IE8 and below but is failing in IE 11. What I need is a way to get the else part working in IE 11. I just cannot figure out what is failing and how to fix it.

Thanks.

Your problem is that fireEvent shouldn't be used in newer IE versions. Support for dispatchEvent was added in IE9. http://help.dottoro.com/ljrinokx.php

if(document.createEventObject) {
    obj_caller.target.fireEvent("onchange");
} else {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
    obj_caller.target.dispatchEvent(evt);
}
