jquery event-handling dynamic-content JavaScript

I need help solving I'm deploying to production and I'm learning this framework and After trying multiple solutions online, I still can't figure this out. I'm working with an scenario with event binding using jQuery's `.on()` method. I have a form that allows users to add multiple sets of input fields dynamically. After cloning the existing set of input fields, I use `.on('change', ...)` to bind a change event to these new inputs. However, the change event is not being triggered for the dynamically added inputs. Here's a simplified version of my code: ```javascript $(document).ready(function() { $('#addFieldButton').on('click', function() { var newFieldSet = $('#inputSet').clone(); newFieldSet.find('input').val(''); // Clear input values newFieldSet.appendTo('#formContainer'); }); $('#formContainer').on('change', 'input', function() { console.log('Input changed: ', $(this).val()); }); }); ``` The initial set of inputs works correctly, but once I clone the input set, the change event does not fire for those new inputs. I've tried different selectors in the `.on()` method and also ensured that the structure remains the same, but to no avail. I'm using jQuery 3.6.0 and testing in Chrome. Is there something I'm missing regarding the event delegation that would prevent the event from firing on newly cloned elements? This is happening in both development and production on Linux. What would be the recommended way to handle this? My team is using Javascript for this REST API. Any ideas what could be causing this? Thanks, I really appreciate it!
