Java JTable Listener onChange

Question

I have my data on MySQL server and I loaded it to Jtable using this code below:

try{
        st= conn.createStatement();
        st.executeQuery(q);
        ResultSet rs = st.executeQuery(q);
        borrowers_list.setModel(DbUtils.resultSetToTableModel(rs)); 
}
catch(SQLException ex){
    JOptionPane.showMessageDialog(null,ex);    
}

My data table has a boolean, and I want it to display in JTable as checkbox. My code works but the table listener does not. I want to have an event everytime there's a changes in checkbox. I used this code below but it doesn't work..

borrowers_list = new JTable(){
    @Override
    public Class getColumnClass(int column){
        for (int row = 0; row < getRowCount(); row++)
        {
            Object o = getValueAt(row, column);

            if (o != null)
            {
                return o.getClass();
            }
        }

        return Object.class;
    }
};

borrowers_list.getModel().addTableModelListener(new TableModelListener() {
    public void tableChanged(TableModelEvent e) {
        // EVENT HERE
    }
});

How can I fix it?
