I have this piece of code: let iFrame = document.getElementById('oc-editor'); iFrame.addEventListener('load', function() { iFrame.contentWindow.postMessage({ eventType: 'populateCode', language: "{{this.codeLang}}", files: [ { "name": "file.{{this.codeLang}}", "c…

Looks like you’re working in gjs, so you can just use glimmer functions instead of trying to work around DOM rendering and race conditions.

Add import { on } from "@ember/modifier"; and this should work. It’s a good idea to look at the Discourse source code. It’s a good place to learn with existing code.
