Event origin

Hello
When an EventListener was added, all element of jplist form run the event.
Could you add a reference to the element who triggered the event ?
Is-it possible to add the previous value and new new value of element ?

Look at the EventListener implementation in the jplist library to understand how events are triggered across all form elements. Identify where the event object is created and see if the triggering element reference can be added. Check if previous and new values of the element are accessible during the event lifecycle. Review existing tests or examples to ensure changes don't break current functionality.
