jquery events select html javascript

I just started working with Quick question that's been bugging me - I'm sure I'm missing something obvious here, but I'm working with an scenario where I'm replacing the HTML content of a `<select>` element using jQuery's `.html()` method, but the `.change()` event doesn't seem to be triggered afterward... I need the relevant event to trigger so that my other functions can react accordingly. Here's my code: ```javascript $('#mySelect').html('<option value="1">Option 1</option><option value="2">Option 2</option>'); ``` I've tried manually triggering the change event with: ```javascript $('#mySelect').change(); ``` But it still doesnโ€™t work as expected. The change event only seems to fire when the user interacts directly with the select box. I noticed that using `.empty().append()` instead of `.html()` gives me the desired behavior, but I want to know if thereโ€™s a more efficient way to handle this. I'm using jQuery version 3.6.0 and this scenario appears across multiple browsers. Is there something I'm missing in my approach, or is there a recommended best practice for updating select elements dynamically while ensuring their events are triggered properly? Any ideas what could be causing this? This is my first time working with Javascript 3.10. How would you solve this? How would you solve this? For reference, this is a production service. What's the correct way to implement this? I'm on macOS using the latest version of Javascript.
