jQuery show / hide不支持克隆的元素集

Question

以下是我的脚本。 .OtherCheck部分是不起作用的。当我添加（克隆）元素集时，它就像.OtherCheck部分没有看到新的元素集或其他东西..如果这是问题，如何使检查始终保持一致？

 $(document).ready(function(){

    $("#RMAForm").validate({
        errorPlacement: function(error,element) {
            return true;
        }
    });

    $("#InvoiceDate").datepicker();

    var textarea = $('.OtherText');
    var textlabel = $('.OtherLabel');
    textarea.hide();
    textlabel.hide();

    $('.OtherCheck').change(function(){
            var selectL = $(this).val();
            if (selectL == 'Other'){
              textlabel.show();
              textarea.show();
            }
            else {
              textlabel.hide();
              textarea.hide();
            }
    });

    var i = 2;

    $("#AddOne").click(function () {
        if (i < 11) {
            var itemNum = "<div class='iSep'>Item "+ i +"</div>";
            $(".cloneSet:first").clone().prepend(itemNum).appendTo("#cloneRet").children(":not(div):not(br)").each(function(){
            $(this).val("");
            var nameAttr = $(this).attr("name") + i;
            var forAttr = $(this).attr("for") +i;
            $(this).not("label").attr("name", nameAttr);
            $(this).not("select").not("textarea").attr("for", forAttr);
            });
            i++;
        }
    });

    $("#RemoveOne").click(function(){
        if (i >= 3 && i <= 11) {
        $(".cloneSet:last").remove();   
        i--;            
        }
    });

  });
