JavaFX、誰かがTableviewのCheckBoxをチェックした場合、どのようにイベントをトリガーするのですか？

Question

私はJavaFXで大きな問題があります。私はTableViewを作成しました。私はいくつかのCheckBoxをTableViewに追加しました。誰かがTableViewのチェックボックスをチェックすると、イベントをトリガーしたいと思います。私はいくつかの方法を試しましたが、私はいつも同じ問題を抱えています。私はプログラムを起動し、GUIを表示する前に "CheckBox trigger event"を5回実行します。その後、私はチェックボックスをクリックすることができますが、何も起こりませんでした。これは私のコードなので、私が助けてくれることを願っています。どうも！
