Passing the type using the data-type attribute

Fix the "Cannot read properties of undefined" error:
- The `function editAdlist(event)` wasn't receiving any arguments,
  because every call to this function is not passing arguments, so
  `event` was undefined.

Using `data-type` attribute to pass the value and avoid the error.
