Answer 1

if you set the onclick via html you need to removeAttr ($(this).removeAttr('onclick'))

if you set it via jquery (as the after the first click in my examples above) then you need to unbind($(this).unbind('click'))

Answer 2

If you use $(document).on() to add a listener to a dynamically created element then you may have to use the following to remove it:

// add the listener
$(document).on('click','.element',function(){
    // stuff
});

// remove the listener
$(document).off("click", ".element");
