<input id="in" type="text">

<script>
var input = document.getElementById("in");

input.oninput = function () {
    console.log("input");
};

input.onchange = function () {
    console.log("change");
};

setTimeout(function () {
    input.value = "test"
}, 5000);
</script>

No events worked.

JavaScript events do not detect when the value is updated with JavaScript. Basically when you change the value, you should trigger your own custom event. – epascarello Sep 20 '16 at 19:25
You need to trigger change event on event in setTimeout or in setTimeout always take first value or input and match value if different – Farhan Sep 20 '16 at 19:36
