How to issue signal each time a row is edited in QListWidget?

Question

class genericTaskList : public QListWidget
{
    Q_OBJECT  
    public:
        QListWidgetItem *defaultText;

        genericTaskList (QWidget *parentWidget)
        {
            setParent      (parentWidget);
            setFixedSize (445, 445);

            defaultText = new QListWidgetItem ("Double click here to compose the task");
            defaultText->setFlags (defaultText->flags () | Qt :: ItemIsEditable);

            insertItem     (0, defaultText);

            QObject :: connect (this, SIGNAL (currentRowChanged (int)), this, SLOT (addDefaultText (int)));
        }

    public slots:
        void addDefaultText (int rr)
        {
            std::cout << "\ndsklfjsdklfhsdklhfkjsdf\n";

            insertItem (++rr, defaultText);
        }
};

This code is supposed to issue a signal each time the row gets edited.

After I call "insertItem" in the constructor, the signal is issued.
But, that's it. It never gets issued after that - no matter how many times I edit the row.

What am I missing?
