Trying to add a page to a notebook


I'm trying to reconstruct the first page of a notebook on a click of a
button in second page.

The problem is that when click, nothing happen. The function works
because the page is constructed when calling from the function main().


#include <gtk/gtk.h>

void end (GtkWidget*, gpointer);
void generateButtons(GtkWidget*, gpointer);

int main(int argc, char *argv[])
    gint i;
    GtkWidget *window, *label, *button, *notebook;

    gtk_init (&argc, &argv);

    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title (GTK_WINDOW (window), "Box example");
    gtk_widget_set_size_request (window, 300, 100);

    g_signal_connect (G_OBJECT(window), "destroy", G_CALLBACK (end), NULL);

    label = gtk_label_new("Page Two");

    button = gtk_button_new_with_label("Click to reconstruct the page one");

    /* Append to pages to the notebook container. */
    notebook = gtk_notebook_new();

    generateButtons(NULL, (gpointer)notebook);
    gtk_notebook_insert_page (GTK_NOTEBOOK (notebook), button, label, 1);

    gtk_container_add (GTK_CONTAINER (window), notebook);
    gtk_widget_show_all (window);

    g_signal_connect (G_OBJECT(button), "clicked", G_CALLBACK
(generateButtons), (gpointer)notebook);

    return 0;

void generateButtons(GtkWidget *widget, gpointer data)
    GtkWidget *vbox, *button, *button1, *label, *notebook = GTK_WIDGET(data);
    vbox = gtk_vbox_new (TRUE, 5);

    button = gtk_button_new_with_label ("John");
    gtk_box_pack_start (GTK_BOX (vbox), button, FALSE, FALSE, 0);

    g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK
(gtk_widget_destroy), (gpointer) button);

    button1 = gtk_button_new_with_label ("Maria");
    gtk_box_pack_start (GTK_BOX (vbox), button1, FALSE, TRUE, 0);

    g_signal_connect (G_OBJECT (button1), "clicked", G_CALLBACK
(gtk_widget_destroy), (gpointer) button1);

    label = gtk_label_new("Page One");

    gtk_notebook_insert_page(GTK_NOTEBOOK(notebook), vbox, label, 0);

void end(GtkWidget *window, gpointer data)
