Issue with the docs

great work...
you have error in the documentation , the function should be with 2 parameters and not one and you use the color and not e.color
demo1.on('changeColor', function(e,color){ if(color==null) $(this).val('transparent').css('background-color', '#fff');//tranparent else $(this).val(color).css('background-color', color); });
