JavaScript Events Not Triggering After Dynamic Element Append

You are encountering an issue where JavaScript events are not firing after appending new elements to the DOM. This is because jQuery only recognizes elements present when it initially runs during page load.

To resolve this, you need to employ event delegation to capture events from dynamic elements. Event delegation involves catching events at a higher level in the DOM that was already there during page load. This allows events from newly added elements to bubble up and be handled.

In your case, you can delegate the click event to a parent element that was present during page load. For example, you could change your JavaScript code to use the on() method as follows:

$(document).on('click', '.races', function(e) {
  // Your code here
});
Copy after login

This way, any new elements added with the class ".races" will inherit the click event handler. Remember to use the on() method instead of click() when implementing event delegation.
