使用Pure JS渲染指令

Question

我正在使用PURE渲染指令（docs）

HTML

  <td class="timer ">
    <span class="active_col_duration1">
    00:00:00
  </span>
  </td>

SCRIPT

 $('.timer').render(obj, directivetimer);

var directivetimer = {
    'span': {
        'act<-active':{

            '.active_col_duration1+': function(arg){
                conf_time_sec = arg.item.duration1;
                if(refreshIntervalId>0)
                    clearInterval(refreshIntervalId);
                refreshIntervalId = setInterval(function(){
                    conf_time_sec = parseInt(conf_time_sec)+1;
                    $(".active_col_duration1").html(("" +conf_time_sec).toHHMMSS());
                },1000);
                return " " +  (""+arg.item.duration1).toHHMMSS();
            },
        }
    }
};

但是，我得到Uncaught pure error: The node ".active_col_duration1+ was not found in the template: <span class="active_col_duration1"。我哪里错了？
