JSF的高手快进来呀..MethodBinding的问题

动态创建一个表格,在UIColumn组件上,通过ValueBinding可以实现值绑定..但是我想在UIColumn上绑定CommandLink组件,然后在往CommandLink上实现方法绑定,就不行啦..不报错,但是方法没绑定上去.....
private void addCommandColumnToTable(FacesContext context,
String columnName, String commandName, String bindingCommand,
UIData table) {
// 新建数据列
  UIColumn column = new UIColumn();
  column.setId("col_" + columnName);
  // 新建header项
  HtmlOutputText header = new HtmlOutputText();
  header.setId("hdr_" + columnName);
  header.setValue(columnName);
  // header.setStyleClass("outputText");
  // 新建文本链接项
  HtmlCommandLink commandlink = new HtmlCommandLink();
  // 绑定动作
  Class[] clas={ActionEvent.class};
  MethodBinding mBinding = context.getApplication().createMethodBinding(
"#{dynamicCreate.clickpln}",clas);
  commandlink.setAction(mBinding);
// commandlink.setType("submit");  
  // 新建命令文本
  HtmlOutputText text = new HtmlOutputText();
  text.setId("output_" + columnName);
  // text.setStyleClass("outputText");
  text.setValue(commandName);
  // 逐加入命令中
  commandlink.getChildren().add(text);
  // 逐个添加项
  column.setHeader(header);
  column.getChildren().add(commandlink);
  // 逐加入表中
  table.getChildren().add(column);
}
高手,,帮我看下这段问题...


下面这段我是直接绑定panelGrid上面,,这段就行..
public HtmlPanelGrid getPanelGrid(){
FacesContext facesContext = FacesContext.getCurrentInstance();
Application application = facesContext.getApplication();
HtmlPanelGrid panelGrid = (HtmlPanelGrid) application
.createComponent(HtmlPanelGrid.COMPONENT_TYPE);
//建立一个文本.
HtmlOutputText outText = (HtmlOutputText)application.createComponent(HtmlOutputText.COMPONENT_TYPE);
outText.setTitle("try_UIC_1");
outText.setValue("Bind");
panelGrid.getChildren().add(outText);
// 建立一个按钮....
        //FacesContext context = FacesContext.getCurrentInstance();
        MethodBinding mb = (MethodBinding) facesContext.getApplication().createMethodBinding("#{dynamicCreate.clickpln}", null);       
        HtmlCommandButton newOne=new HtmlCommandButton();
        newOne.setValue("DynaButton");
        newOne.setAction(mb);
        panelGrid.getChildren().add(newOne);
        panelGrid.setColumns(1);
return panelGrid;
}
