Event listener HTML element generated after iframe load

Hello,

My interface loads the verge3d iframe when the page loads but I also generate some html elements after user interactions with the page and thus after all the verge3d elements and scripts have already loaded.

This means some HTML event listener from the visual logic refer to items generated later on on the page via javascript. When the visual logic is loaded these items do not exist yet. Is there a way to re-assign the visual logic on elements with javascript or any other method after the iframe has already loaded ?

Thank you for your help
