Как сообщить jquery что dom изменен?

$('.cart-list>li').click(function(e){
		e.preventDefault();
		var price = parseInt($(this).children('price').text());
		var total = parseInt($('.total>b').text());
		var bigTotal = parseInt($('.big-total>b').text());
		$('.total>b').html(total-price+'<i class="ico ico-rub"></i>');
		$('.big-total>b').html(total-price+350+'<i class="ico ico-rub"></i>');
		$(this).remove();
	});

$('.buy').click(function(e){
		e.preventDefault();
		var addItems = $(this).data();
		// console.log(addItems.img);
		$('.cart-list').append('<li><img src="'+addItems.img+'" class="img-small" alt=""><tt>'+addItems.title+'</tt><span>1</span><i class="ico ico-times"></i><price>'+addItems.price+'&nbsp;<i class="ico ico-rub"></i></price><a class="del" href="#"><b class="ico ico-trash"></b></a></li>');
	});
