Works fine, thank you for your help, I have forgotten to set "editable"
to TRUE.

I join a small example if someone need help :

------
#include <gtk/gtk.h>

enum { 
        C_STRING,
        C_TEXT_COLUMN,
        NB_COLUMN 
};


static void
combo_edited_cb (GtkCellRendererText *cell, const gchar *path,
                 const gchar *value, GtkListStore *list)
{
        g_debug("COMBO_EDITED_CB");
}

GtkWidget* create_list(void)
{
        GtkListStore *list_store;
        GtkWidget *list;
        GtkCellRenderer *renderer;
        GtkListStore *list_store_combo;
        GtkTreeIter iter;

        list_store = gtk_list_store_new (NB_COLUMN,
                                         G_TYPE_STRING,
                                         G_TYPE_UINT);
        gtk_list_store_append (list_store, &iter);
        gtk_list_store_set (list_store, &iter, 0, "First Item (default)", -1);

        list = gtk_tree_view_new_with_model( GTK_TREE_MODEL (list_store));

        g_object_unref (list_store);

        /* Combo */
        renderer = gtk_cell_renderer_combo_new ();

        list_store_combo = gtk_list_store_new (1, G_TYPE_STRING);
        gtk_list_store_append (list_store_combo, &iter);
        gtk_list_store_set (list_store_combo, &iter, 0, "First Item", -1);
        gtk_list_store_append (list_store_combo, &iter);
        gtk_list_store_set (list_store_combo, &iter, 0, "Second Item", -1);
        gtk_list_store_append (list_store_combo, &iter);
        gtk_list_store_set (list_store_combo, &iter, 0, "Third Item", -1);

        g_object_set (G_OBJECT (renderer), 
                      "model", list_store_combo,
                      "editable", TRUE,
                      NULL);
        g_signal_connect (G_OBJECT (renderer), 
                          "edited",
                          G_CALLBACK (combo_edited_cb), 
                          list_store);
        gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW(list), -1,
                                                     "Combo", renderer,
                                                     "text", C_STRING,
                                                     "text-column", C_TEXT_COLUMN,
                                                     NULL);
        
        return list;
}

int main (int argc, char **argv)
{
        GtkWidget *window;
        GtkWidget *list;
        
        gtk_init (&argc, &argv);

        /* Create window, etc */
        window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
        g_signal_connect (window, "destroy",
                          G_CALLBACK(gtk_main_quit),
                          NULL);

        list = create_list ();
        gtk_container_add (GTK_CONTAINER (window),
                           list);

        gtk_widget_show_all (window);
        
        gtk_main ();
        
        return 0;
}
