On the checkout page in Magento 2

After search data by finder code, it auto fill customers data.
But when I click the "Next" button. It will show "This is a required field."

var elem = document.getElementById("input");
 elem.value = "new value";
 ko.utils.triggerEvent(elem, "change");

For example my code


I want to know about "ko.utils.triggerEvent" by jQuery not element
