ckeditor click event does not work

I have a ckeditor plugin and inside the init: I want to capture the click event so I can do something.

CKEDITOR.plugins.add('Columns',{
  init : function(editor) {
    editor.on('doubleclick', function(ev) {console.log('hello');}); // Works
    editor.on('focus', function(ev) {console.log('hello');}); // Works

    editor.on('click', function(ev) {console.log('hello');}); // Does not work
    editor.on('mousedown', function(ev) {console.log('hello');}); // Does not work
  }
});

Any Ideas???

EDIT: OK could not get click working, I believe we need to create an event for that. However thanks to this post: http://alfonsoml.blogspot.com.au/2011/03/onchange-event-for-ckeditor.html

I managed to use 'saveSnapshot' which seems to fire each time I click so this now works

editor.on('saveSnapshot', function(ev) {console.log('hello');}); // Works
