I've searched everywhere and can't find a clear answer. Hey everyone, I'm running into an issue that's driving me crazy. I'm working with an scenario where I'm trying to attach a click event handler to buttons that are being dynamically added to a container. Initially, the buttons are present in the DOM and the click event works fine. However, when I clear the container using `.empty()` and then repopulate it with new buttons, the click event no longer fires. Here's what my code looks like: ```javascript $(document).ready(function() { // Initial button creation $('#container').append('<button class="dynamic-btn">Click me</button>'); // Event handler for dynamically created buttons $('#container').on('click', '.dynamic-btn', function() { alert('Button clicked!'); }); // Simulate clearing and recreating the buttons $('#clear-btn').on('click', function() { $('#container').empty(); // Repopulating the container $('#container').append('<button class="dynamic-btn">New Button</button>'); }); }); ``` I've tried moving the event handler setup to include it after the `.empty()` call, but that doesn't seem to work either. I'm also aware of event delegation and thought that using `.on()` would help in this scenario, but it seems like the reference to the buttons is lost after the `.empty()` call. When I debug, the event handler seems to be properly bound initially, but it doesn't trigger after the buttons are recreated. Is there something I'm missing or a best practice for handling dynamic elements in such a case? Any insights would be greatly appreciated! Any help would be greatly appreciated!
