Need an event to fire when selecting index in dropdown in JavaScript

I need an event in JavaScript which will fire when something is selected from dropdown. I am using onchange now, it does almost everything I want, but when I am clicking my dropdown and select index that was already selected, it won’t fire. And I need an event that acts like onchange, but fires every time even when I am selecting already selected option.

Is there something like that in JS?
