jquery event-delegation dynamic-content JavaScript

I've been working on this all day and I'm relatively new to this, so bear with me. Hey everyone, I'm running into an issue that's driving me crazy. I'm relatively new to this, so bear with me. I'm working with an scenario where the jQuery `.on()` event handlers I set up for specific elements are not firing when those elements are replaced with new content using `.html()`. I have a table where rows can be dynamically updated, and I want to maintain the click event on a button inside each row. Here’s a simplified version of my code: ```javascript $(document).ready(function() { // Initial setup of click event on button inside table rows $('#myTable').on('click', '.myButton', function() { alert('Button clicked!'); }); // Simulate replacing the table content with new rows $('#replaceButton').click(function() { $('#myTable').html('<tr><td><button class="myButton">New Button</button></td></tr>'); }); }); ``` When I click the `#replaceButton`, the new rows are added, but clicking the button inside the new row does not trigger the alert. I’ve confirmed that the new button exists in the DOM after the replacement, but the event doesn’t seem to bind correctly. I've also tried using `.empty()` and then appending new content, but the scenario continues. Is there something specific I’m missing with event delegation here? I’ve tried checking for event propagation or using `.delegate()` method, but it seems unnecessary if `.on()` is supposed to handle this. This is happening in jQuery version 3.6.0, and I'm testing the code in Chrome. Any help would be appreciated! My development environment is Linux. This is happening in both development and production on CentOS. Any examples would be super helpful. I'm working on a desktop app that needs to handle this. Thanks in advance! This is part of a larger web app I'm building. Any help would be greatly appreciated! Thanks in advance!
