Как добавить сигнал к собственному QListWidgetItem

Пытаюсь добавить сигнал к собственному QListWidgetItem, но ничего не работает.

connect(ui->listWidget, SIGNAL(itemClicked(MyListBoxItem*)), this, SLOT(on_listWidgetItemClicked(MyListBoxItem*)));

mylistboxhitem.h

#ifndef MYLISTBOXITEM_H
#define MYLISTBOXITEM_H

#include <QListWidget>
#include <QListWidgetItem>

class MyListBoxItem : public QListWidgetItem
{
public:
    MyListBoxItem(QListWidget *parent = 0);
    ~MyListBoxItem() {};
    void setId(int id);
    int getId();
private:
    int id;
};

#endif // MYLISTBOXITEM_H

mylistboxhitem.cpp

MyListBoxItem::MyListBoxItem(QListWidget *parent) : QListWidgetItem(parent)
{

}

void MyListBoxItem::setId(int id)
{
    this->id = id;
}

int MyListBoxItem::getId()
{
    return this->id;
}

connect

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

     // Меню  
    =================================================================================
    connect(ui->New, SIGNAL(triggered()), this, SLOT(actionTrigger_New()));
    connect(ui->Load, SIGNAL(triggered()), this, SLOT(actionTrigger_Load()));
    connect(ui->Save, SIGNAL(triggered()), this, SLOT(actionTrigger_Save()));
    connect(ui->Calculate, SIGNAL(triggered()), this, SLOT(actionTrigger_Calculate()));
    connect(ui->Exit, SIGNAL(triggered()), this, SLOT(actionTrigger_Exit()));
// =======================================================================================
// QListWidget
connect(ui->listWidget, SIGNAL(itemClicked(MyListBoxItem*)), this, SLOT(on_listWidgetItemClicked(MyListBoxItem*)));
}

Выводит в консоль

No such signal QListWidget::itemClicked(MyListBoxItem*) in ...
