Update custom field when an issue is cloned

Tools Admin

I am wanting to update a custom field from "Yes" to "No" when the issue is cloned. I have been looking for examples of this online for several hours and can't find anything to start from. 

I will be using behaviours on this field so that it is only editable by a group of users.

I would recomend to create event listener on issue creation event. 

Into handler you should checks wether an issue just created or it was cloned.
