Define onKeydown function for the buttons "OK" and "Cancel" on linb.Alert

[saulomartins]

Hello!
How can i define onKeydown function for the buttons "OK" and "Cancel" on linb.Alert ?
This is my code example:

    linb.alert("Err","Test").ok.onKeydown(function() {alert('clicked on ok');});     linb.alert("Err","Test").cancel.onKeydown(function() {alert('clicked on cancel');});

Please can you show me an example?
Thank you!

There's only a onclick event:

linb.UI.Dialog.alert('title','content',function(){
     linb.message('close');
})

Ok, Thank you!!!
In this case i will use javascript alert('Test');
