Multiple buttons in one table column in Java Swing won't perform action

Question

What I need is to dynamically add buttons to one JTable column. Each row can have 0-N buttons in this column. I figured how to add these buttons but after clicking on them nothing happens, despite each button has action listener specified.

In addition, right after I create these buttons I need to set ActionListeners to it, so that when this button is clicked, some action will be done (action outside of TasksCell class).

Here is how I set renderer and editor and how I create buttons :

table.setDefaultRenderer(Tasks.class, new TasksCell());
table.setDefaultEditor(Tasks.class, new TasksCell());
//
//
// 
ActionListener listener = new AbstractAction() {
        @Override
        public void actionPerformed(ActionEvent e) {
            // DOING STH
        }
    };
    
JButton button = new JButton("task");
button.addActionListener(listener);

// tableModel is custom TableModel
tableModel.addNewTask(button);

This is how I add task(button) to my class for storing buttons in my custom table model:

// I need to calculate where to add button, row is index of the row in table
((Tasks)this.getValueAt(row, 3)).addTask(task);

Then this is my class for storing buttons :

public class Tasks {

    private List<JButton> taskButtons = new ArrayList<>();

    public void addTask(JButton task) {
        taskButtons.add(task);
    }

    public List<JButton> getTaskButtons() {
        return taskButtons;
    }

    public void setTaskButtons(List<JButton> tasks) {
        this.taskButtons = tasks;
    }

}

And finally class with table cell editor and renderer :

public class TasksCell extends AbstractCellEditor implements TableCellEditor, TableCellRenderer {
    
    @Override
    public Object getCellEditorValue() {
        return null;
    }

    @Override
    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
        Tasks tasks = (Tasks)value;
        
        JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
        
        tasks.getTaskButtons().forEach(task -> {
            panel.add(task);
        });
        
        panel.setBackground(table.getSelectionBackground());
        return panel;
    }

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        Tasks tasks = (Tasks)value;
        
        JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
        
        tasks.getTaskButtons().forEach(button -> {
            panel.add(button);
        }); 
        
        panel.setBackground(isSelected ? table.getSelectionBackground() : table.getBackground());
        return panel;
    }
}

As I mentioned before, buttons are added to panel in table correctly
