Rally JS SDK刷新监听器

Question

如果是WSJF应用程序，该应用程序未正确排序列，它完全忽略0并且仅在单击列名称时对正的非零数字进行排序。所以我试图使用"refresh"监听器编写自己的排序。我的问题是，刷新监听器如何知道单击了哪个列触发了监听器？

刷新侦听器如下：

refresh: function(this,eOpts){
  //I need to check which column was clicked, (both this and eOpts) are returning objects but none has values that I can use.
}
