cloneNode() does not copy event listeners. In fact, there's no way of getting hold of event listeners via the DOM once they've been attached, so your options are:

• Add all the event listeners manually to your cloned node


• Refactor your code to use event delegation so that all event handlers are attached to a node that contains both the original and the clone


• Use a wrapper function around Node.addEventListener() to keep track of listeners added to each node. This is how jQuery's clone() method is able to copy a node with its event listeners, for example.
