2. (function($, window, undefined ) {
3. 
   
4.       // do stuff
5. 
   
6. })( jQuery, this )

 I'm trying to create a very simple plugin to control the pulse (fadeIn()/fadeOut()) effect and use a callback. The pulse itself works, but the callback doesn't. I'm not sure what i'm doing wrong?

 (function($){

	$.fn.pulse = function(options) {

		return this.each(function(){

			var
				$this = $(this),
				settings = $.extend({}, $.fn.pulse.defaults, options);
	
			$this
				.fadeIn(settings.speed,function(){
					for(var n=settings.count-1; n>=0; n--){
						$(this)
							.fadeOut(settings.speed)
							.fadeIn(settings.speed,function(){
								if(n == 0){
									settings.callback(); // not working!
								}
							});
					}
				});
		});
	};

	$.fn.pulse.defaults = {
		count : 3,
		speed : 'fast',
		callback : function(){alert('Done!')}
	};

})(jQuery);
