I got it to work by using gtk_signal_connect_after()
I don't know if it's the right way to do it, but it seems to work.

#include <gtk/gtk.h>

gint text_button_press_cb (GtkWidget      *text,
                           GdkEventButton *event,
                           gpointer        data)
{
        GtkWidget *popup_menu = GTK_WIDGET (data);

        if (event->button == 3) {
                gtk_menu_popup (GTK_MENU (popup_menu),
                                NULL, 
                                NULL, 
                                NULL, 
                                NULL,
                                event->button, 
                                event->time);
                return TRUE;
        }

        return FALSE;
}

gint menu_item_activate_cb (GtkWidget *menuitem, gpointer data)
{
        GtkWidget *label = GTK_BIN (menuitem)->child;
        gchar *label_string;

        gtk_label_get (GTK_LABEL (label), &label_string);
        g_print ("%s\n", label_string);

                label_buffer = g_strdup_printf ("menuitem - %d", i);
                label = gtk_label_new (label_buffer);
                g_free (label_buffer);
