i have a perl/tk program witch is just a text widget, and a button, and i want the text to change everytime i click the button. so i need to be able to change the command of the button each time it is clicked, does anybody know how to do this? here is the code:

#!/usr/bin/perl 

use strict;
use warnings;
use Tk;

sub one;

my $main = MainWindow->new;

my $label1 = $main->Text
(
    '-width'=>'50'
)->pack;

my $button = $main->Button
(
    -text=>'next',
    -command=>sub{one}
)->pack;

MainLoop;

sub one
{
    my $talk2="number1";
    my $talk="this text will be changing after every click of the butt
+on.";
    $label1 -> insert('1.0',"$talk");
    my $button = $main->Button(-text=>'next',-command=>sub{two})->pack
+;
}

sub two
{
# change the text box again
}
