      return {
        reset: function() {
          count = 1;
          warehouse = {};
        },
        set: function (dom, data) {
          if (!dom.__data) {
            dom.__data = "hello" + count++;
          }
          warehouse[dom.__data] = data;
        },
        get: function(dom) {
          return warehouse[dom.__data];
        }
      };
    }();
    
    div.setAttribute('data-po', 'to');
    div.setAttribute('data-ta', 'ma');
