jquery event-delegation dynamic-content javascript

I can't seem to get I tried several approaches but none seem to work..... I just started working with After trying multiple solutions online, I still can't figure this out. I'm working with an scenario where I'm trying to use jQuery's `.on()` method to attach click events to dynamically created buttons that have custom data attributes. I have a list of items that, when clicked, should generate a button with a data attribute that contains the item ID. However, the click event doesn't seem to fire for these buttons after they've been added to the DOM. Here's the relevant part of my code: ```javascript $(document).ready(function() { $('#itemList').on('click', '.item', function() { // Get the item ID var itemId = $(this).data('id'); // Create a new button with a data attribute var newButton = $('<button/>', { text: 'Click Me', class: 'dynamic-button', 'data-id': itemId }); $('#buttonContainer').append(newButton); }); // Attempting to attach click event to the new button $('#buttonContainer').on('click', '.dynamic-button', function() { alert('Button clicked! Item ID: ' + $(this).data('id')); }); }); ``` In this code, the click event for the `.dynamic-button` is not firing. I’ve verified that the button is being created and appended properly by checking the DOM elements in the browser's developer tools. I also tried using `$(document).on('click', '.dynamic-button', function() {...})`, but it didn't help either. I suspect it might be a scoping scenario or related to how the event delegation is handled, but I can’t pinpoint the cause. The jQuery version I’m using is 3.6.0. Any insights on how to get this working would be greatly appreciated. What are your experiences with this? This issue appeared after updating to Javascript stable. Thanks for any help you can provide!
