Why is nothing happening?

I have written all this code down, and the class has been changed to 'responded' but the list item does not get any styling can someone help and explain why this is?

const form = document.querySelector('#registrar');
const input = form.querySelector('input');
const ul = document.querySelector('#invitedList');
const li = document.createElement('li');

form.addEventListener('submit', function submit(name) {
  name.preventDefault();
  const text = input.value;
  input.value = '';
  li.textContent = text;
  const label = document.createElement('label');
  label.textContent ='Confirmed';
  const checkbox = document.createElement('input');
  checkbox.type = 'checkbox';  
  label.appendChild(checkbox);
  li.appendChild(label);
  ul.appendChild(li);
  input.value = '';
});

ul.addEventListener('change', function styling(e) {
  const checkbox = e.target;
  const checked = e.checked;
  const listItem = checkbox.parentNode.parentNode;
  if (checked) {
    listItem.clasName = 'responded';
  } else {
    listItem.className = '';
  }
});

There are two things to fix in ul.addEventListener

const checked = e.checked;

should be

const checked = e.target.checked;

and

listItem.clasName = 'responded';

should be

listItem.className = 'responded';

Thank you! Can't believe I spent so much time trying to find out what was wrong only to find out they were typos! :-)
