Crash application on set_text() for GtkEntry

[danilo]

Good evening.
I've just started to study how work PHP-GTK2. I try to fill a GtkEntry with some text after click a button. The Gtk interface is very simple: a button in the bottom of the form and a GtkEntry on the top. On the click of the button, in the text-field will appear some text (the classic 'Hello World'). The problem is that when I click on the button, the form close itself without an error or warning.
I load the GUI from a .glade file (Glade version 2.12.1 for windows).
In detail, my code is:
*******************************
<?php
// Create a new glade instance, load the
// widgets from the file passed as parameter
$glade = new GladeXML('testglade.glade');

//Again, get the widget object and connect the clicked signal
$button = $glade->get_widget('button1');
$nome = $glade->get_widget('entry1');

// Connection signal->function
$button->connect_simple('clicked', 'onClickButton');

//This method is called when the button is clicked
function onClickButton() {
$nome->set_text('Hello world!');
$nome->grab_focus();
}


//Start the main loop
Gtk::main();
?>

*******************************
and the .glade (testglade.glade) file is:

What is wrong ?
Thank you in advance for your help.

$nome is not available in the method.

Thank you very much !

If it can be useful to other people, follow the correct code:
**************************************
<?php

// Create a new glade instance, load the
// widgets from the file passed as parameter
$glade = new GladeXML('testglade.glade');

//Again, get the widget object and connect the clicked signal
$button = $glade->get_widget('button1');
$nome = $glade->get_widget('entry1');

// Connection signal->function
$button->connect_simple('clicked', 'onClickButton', $nome);

//This method is called when the button is clicked
function onClickButton($nome) {
$nome->set_text('Hello world!');
$nome->grab_focus();
}

//Start the main loop
Gtk::main();
?>

**************************************
Other possibility was to declare $nome as global in the function (not really nice...)
