触发事件处理程序附加到它自己的对象，但在链中？

Question

现在我有：

$("#myElement").bind("buildTimeline", function (event, newViewObj) {
    curDomObj = $(this).children(".timeline"); //this refers to #myElement

    curDomObj.draggable({
        axis:"x",
        drag:curDomObj.trigger("drag")
    });
});

我宁愿只有一条链，但是有没有办法在链中的位置引用当前元素？：

$(this).children(".timeline").draggable({
    axis:"x",
    drag:$(this).trigger("drag") //this still refers to #myElement, but I want
                                 //it to refer to #myElement .timeline
});

怎么样：

$("#myElement").bind("buildTimeline", function (event, newViewObj) {
    $(this).children(".timeline").draggable({
        axis:"x",
        drag:$(this).children(".timeline").trigger("drag")
    });
});
