在jstreegrid中动态创建的selectBox的问题

Question

我已经在我的项目中实现了jstreegrid。我正在网格中动态创建选择框。当我单击selectBoxes时，它立即打开并折叠，而我无法选择选项。但是当我双击它时，它保持打开状态，我可以选择该选项。 在开发人员工具中进行检查时，我发现单击selectBox会刷新包含它的整个div。我认为是造成问题的原因，但不确定。

下面是我的代码。我也有工作的jsFiddle。

var jsonData = [{
    "id": "6345",
    "text": "ActionType",
    "parent": "6343",
    "data": {
         "data_needed": "Y"
     }
},
{
     "id": "6343",
     "text": "GeopoliticalInfo",
     "parent": "6342",
     "data": {
         "data_needed": "N"
      }
},
{
     "id": "6342",
     "text": "BrunnelName",
     "parent": "6267",
     "data": {
        "data_needed": "N"
      }
},
{
     "id": "6267",
     "text": "RoadElement",
     "parent": "#",
     "data": {
         "data_needed": "N"
     }
},
{
     "id": "6344",
     "text": "GeopoliticalView",
     "parent": "6343",
     "data": {
         "data_needed": "Y"
      }
}];

var optionList =["Option1","Option2","Option3","Option4"];

function getOptions(id){
  var combo = $("<select></select>").attr("id",id);
  var option = new Option("--Select--", "");
  combo.append($(option));
   for (var i = 0; i < optionList.length; i++) { 
       option = new Option(optionList[i],optionList[i]);
       combo.append($(option));
   }
    return combo;
