How to add event listener for checkbox in Chrome extension's popup?

I'm trying to capture changes of checkbox in popup of my Chrome Extension. Documentation says:

Inline JavaScript will not be executed

There is an example provided on the same page, but it for button. I don't know how to modify it so it would capture chekbox's state changes.

document.addEventListener('DOMContentLoaded', function () {
      document.querySelector('button').addEventListener('click', clickHandler);
});
