jquery event-delegation dynamic-content JavaScript

I'm stuck on something that should probably be simple. I'm working with an scenario where I'm using jQuery's `.toggleClass()` method to add or remove a class from a button based on specific conditions. However, it only works for buttons that are present in the DOM at the time of the initial script execution and fails for dynamically added buttons later. Here's what I have: ```javascript $(document).ready(function() { $('#myButton').on('click', function() { $(this).toggleClass('active'); }); // Dynamically adding buttons $('#addButton').on('click', function() { $('#buttonContainer').append('<button class="dynamicButton">Dynamic Button</button>'); }); }); ``` The question arises when I click on a dynamically added button; it doesn't toggle the class. I tried changing my event listener to use event delegation like this: ```javascript $(document).ready(function() { $('#buttonContainer').on('click', '.dynamicButton', function() { $(this).toggleClass('active'); }); }); ``` But it still doesn't work. I checked that the buttons are being added correctly, and I can see them in the DOM using the browser's dev tools. The class does not toggle, and there are no errors in the console. I suspect it might be related to how jQuery handles the event delegation or if there are any issues with the timing of the jQuery library loading. I'm using jQuery version 3.6.0. Any insights on why this might be happening or how I can get the `.toggleClass()` to work for dynamically added elements? I’m looking for a reliable solution. Any help would be greatly appreciated!
