How to set click handler on readonly checkbox?

I have to catch clicking event on readOnly checkbox .

At first, setting readOnly: true in config does not set checkbox to be readonly.

So I call checkbox.setReadOnly(true). This works - checkbox becomes readonly.

But neither of 'click', 'change' or 'check' fire when clicking on readOnly checkbox.

How can I catch click event on readonly checkbox? May be it's possible only by assigning click on its container or corresponding input dom element?
