Yeah, you need to reset the $text->editModified(0) flag. The "gotcha" comes when you try to reset the flag automatically at the end of the <<Modified>> callback. You will get an infinite loop. So you need to manually reset it somehow, maybe with a timer? 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::Text;

my $MW = MainWindow->new(
    -title  => "Tk::Text test",
    -width  => 200,
    -height => 200
);
my $text = $MW->Text(
    -height => 10,
    -width  => 40,
    -wrap   => 'word'
);
$text->pack( -side => 'top', -fill => 'both' );
$text->bind( '<<Modified>>' => sub {
                   getText( $text, @_ );
                   } );

$MW->Button(-text=>'Clear Modified Flag',
            -command => sub{  $text->editModified(0) }
            )->pack();

MainLoop;

sub getText {
    my ( $t, @args ) = @_;
    my $text = $t->get( '0.0', 'end' );
    print "Got: $text\n";
    return if ( !$text );
    return 1;
}
