// CORRECAO

var id = 1;
for (var i = 0; i < products.length; i++) {
	if (contains(offsetX, offsetY, products[i], 4)) {
		var productName = products[i].name

		var button = $('<button></button>').
			prop("class", "btn btn-xs btn-danger").
			click((function(id) {
				return function() {
					clean(id, productName);
				}
			})(id)).
			text("X");

		var span = $('<span></span>').
			addClass("pull-right").
			append(button);

		var li = $('<li></li>').
			prop("id", "info" + id).
			prop("class", "list-group-item clearfix").
			text(productName).
			append(span);

		$("#info").append(li);
		id++;
	}
