JavaFX tableview中的复选框单元格

我尝试在使用FXML的tableview中创建复选框单元格。复选框显示但不活动。点击它不会改变它的状态。这是我FXML文件JavaFX tableview中的复选框单元格

，这是我CheckBoxCellFactory.java

package sample; 
import javafx.beans.property.BooleanProperty; 
import javafx.beans.property.ObjectProperty; 
import javafx.beans.value.ObservableValue; 
import javafx.geometry.Pos; 
import javafx.scene.control.TableCell; 
import javafx.scene.control.TableColumn; 
import javafx.scene.control.cell.CheckBoxTableCell; 
import javafx.util.Callback; 
public class CheckBoxCellFactory<S, T> implements Callback<TableColumn<S, T>, TableCell<S, T>> { 
    @Override 
    public TableCell<S, T> call(TableColumn<S, T> p) { 
     CheckBoxTableCell<S, T> cell = new CheckBoxTableCell<S, T>(){ 
      private ObservableValue<T> ov; 
      @Override 
      public void updateItem(Object item, boolean empty) { 

       super.updateItem((T) item, empty); 
       if (item == null) { 
        super.setText(null); 
        super.setGraphic(null); 
       } 
       else { 
        if (ov instanceof BooleanProperty) { 
          super.selectedStateCallbackProperty().unbindBidirectional((ObjectProperty) ov); 
        } 
        ov = getTableColumn().getCellObservableValue(getIndex()); 
        if (ov instanceof BooleanProperty) { 
          super.selectedStateCallbackProperty().bindBidirectional((ObjectProperty) ov); 
        } 
       } 

      } 
     }; 
     cell.setAlignment(Pos.CENTER); 
     return cell; 
    } 
}

我做什么了？

public class TestCase extends RecursiveTreeObject<TestCase> { 

// SimpleBooleanProperty 
private SimpleBooleanProperty isSelected;} 

TreeTableColumn<TestCase, Boolean> selectColumn = new TreeTableColumn<>("Select"); 


    selectColumn.setCellFactory(CheckBoxTreeTableCell.forTreeTableColumn(selectColumn)); 
    selectColumn.setCellValueFactory(param -> { 
     return param.getValue().getValue().getIsSelected(); 
    }); 

    selectColumn.setOnEditCommit((CellEditEvent<TestCase, Boolean> t) -> { 
     ((TestCase) t.getTreeTableView().getTreeItem(t.getTreeTablePosition().getRow()).getValue()).getIsSelected() 
       .set(t.getNewValue()); 
     // refreshTable(t); 
    });
