Attempting to duplicate a div containing input fields but the event listeners are not functioning.
Despite performing a deep copy in the following manner -
let rows = document.querySelectorAll('.row');
let dupNode = rows[0].cloneNode(true);
sheet.appendChild(dupNode);

Every input field has a click event attached, however, the cloned inputs do not seem to be recognizing the click event. What could I be overlooking?
To easily handle multiple elements without binding events individually, simply attach a single event listener to the container with the id #sheet. By utilizing event bubbling, you can add as many new elements as needed without having to bind events to each one:
document.querySelector('#sheet').addEventListener('click', function(e) {
var target = e.target;
if (target.tagName == 'INPUT') {
alert("clicked");
}
}, false);
An important aspect is determining which specific element triggered the event and executing your code accordingly only on those elements of interest.
One important thing to note is that event handlers are not duplicated when an element is cloned. In order for the event handlers to continue working throughout the entire DOM after cloning, you will need to delegate them.
