Twitter Bootstrap Modal on close

Question

So I have a form in a Twitter Bootstrap modal and I want to trigger an event before the modal is closed. For instance, I want to check if he has any value on any of the inputs. If there is, I use confirm(message) to check if the user wants to lose the data or not. Is there anyway to catch this event?

In the documentation there is those event : Bootstrap modal events

$('#exampleModal').on('hide.bs.modal', function (event) {
    if($(this).find("form input").filter(function(){
        return $(this).val() != "";
    }).size() > 0){
       var r =  confirm("Do you want to proceed");
        if(!r){
            event.preventDefault();
        }

    }
});
