        var list2 = $("#callDatatable").find("input[type='checkbox']:checked");
        var list2Data = [];
        $(list2).each(function(index0, data) {
            var name = $(this).parents("tr").find("td:nth-child(2)").text();
            list2Data.push(name);
        });
        var listData = [];
        $(list).each(function(index, data){
            var name = $(this).parents("tr").find("td:nth-child(2)").text();
            var num = parseInt($(this).parents("tr").find("td:last-child").text());
            var newlist = list2Data.slice(0,num);
            list2Data.splice(0,num);
            listData.push({name:name, list: newlist});

        });
