Can't determine if cancel button have been click in a prompt box

[rconcil]

Following this example http://jsfiddle.net/8vdvo13m/10/
I'm enable to determine if the cancel button have been clicked.
Usually null is returned when you click cancel in a prompt but here the text in the input is returned.

Every messagebox has callback option which is called when button is clicked. It takes 3 parameters:

• Lobibox instance
• button key
• event

If you listen to this callback you will know which button is clicked.

Lobibox.prompt('text',
            {
                title: 'Test de prompt',
                attrs: { 
                    placeholder: 'Placeholder text'
                },
                beforeClose: function (lbb) {
                    if(lbb.getValue().length > 0) {
                        alert('We have something');
                    } else {
                        alert('We have nothing');
                    }
                },
                callback: function(box, btn){
                        //btn will be ok or cancel depending which button you clicked
                    console.log(box, btn);
                }
            });

The callback function resolved my problem.
Thanks a lot for your explanation!
