gtk_button_set_label does not change the label

[ghum]

Hello,

I am trying to change button label with gtk_button_set_label. the code
doesn't  output any error messages, but the label doesn't change.
Here is code:

#include <gtk/gtk.h>

void pradetibutton_clicked (GtkWidget *proglog, GtkTextBuffer *logbuffer,
GtkWidget *pradetibutton, gpointer data)
{
        GtkTextIter start, end;
        gtk_text_buffer_get_bounds (logbuffer, &start, &end);
        gtk_text_buffer_set_text (logbuffer, "pakeistas tekstas", -1);
        gtk_button_set_label (GTK_BUTTON(pradetibutton), "baigti");

        while (g_main_context_iteration (NULL, FALSE));
}
void destroy(GtkWidget *widget, gpointer data)
{
        gtk_main_quit ();
}

int main( int argc, char *argv[])
{
        gtk_init (&argc, &argv);
        GtkWidget *window;
        GtkWidget *vbox1;
        GtkWidget *hbox1;
        static GtkWidget *pradetibutton;
        GtkWidget *proglog;
        GtkTextBuffer *logbuffer;
        GtkWidget *scwind1;
        gtk_init(&argc, &argv);
        
        gtk_init (&argc, &argv);
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
        gtk_window_set_title(GTK_WINDOW(window), "DP2");
        gtk_window_set_default_size(GTK_WINDOW(window), 500, 300);
        gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
        g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (destroy),
NULL);  

        vbox1=gtk_vbox_new (FALSE,5);
        gtk_container_add (GTK_CONTAINER (window), vbox1);

        hbox1=gtk_hbox_new (FALSE,5);
        gtk_box_pack_start (GTK_BOX(vbox1),hbox1,FALSE, FALSE, 1);
        pradetibutton = gtk_button_new_with_label ("pradėti");
        
        
        gtk_box_pack_start (GTK_BOX(hbox1),pradetibutton,FALSE, FALSE, 1);
        
        proglog = gtk_text_view_new();
        logbuffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (proglog));
        gtk_text_buffer_set_text (logbuffer, "Hello, this is some text", -1);
        scwind1 = gtk_scrolled_window_new(NULL, NULL);
        gtk_box_pack_end (GTK_BOX(vbox1),scwind1,TRUE, TRUE, 3);
        gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW (scwind1),
proglog);
        gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scwind1),
GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);
        g_signal_connect (G_OBJECT (pradetibutton), "clicked", G_CALLBACK
(pradetibutton_clicked), logbuffer);
        gtk_widget_show (scwind1);
        gtk_widget_show (proglog);
        gtk_widget_show (pradetibutton);
        gtk_widget_show_all(window);

        gtk_main();

        return 0;
}

thanks
