jQuery .on() optimization guide for custom events triggered by third-party library

jquery events third-party-library javascript

I'm having trouble with jQuery's `.on()` method not capturing custom events that are triggered by a third-party library I'm using. The library emits a custom event called `customUpdate` which I want to listen for, but my jQuery event handler does not execute as expected. Here's the setup I'm using: ```javascript // Initializing the third-party library const myLibrary = new ThirdPartyLibrary(); // Attempting to capture the custom event on a specific element $('#myElement').on('customUpdate', function(event, data) { console.log('Custom event triggered!', data); }); // Triggering the custom event from the library myLibrary.trigger('customUpdate', { message: 'Hello, world!' }); ``` Despite calling `myLibrary.trigger()` and expecting the event handler to execute, I'm seeing no output in the console. I double-checked that `#myElement` exists in the DOM when I set up the event listener, and it does. I also verified that the event is indeed being triggered by the library by adding a `console.log` right before the trigger call, and that logs as expected. I've experimented with using `.one()` instead of `.on()`, but that didn't change anything. Additionally, I've tried using `$(document).on('customUpdate', ...)` in case the event was bubbling up, but that also didn't work. The third-party library documentation mentions that the event should be compatible with jQuery event handling, so I'm not sure what I'm missing here. Has anyone else encountered a similar scenario or have suggestions on how to debug this further?
