OnChangeAjaxBehavior applies only to AbstractTextComponent. Such
components are: TextField and TextArea.
HiddenField is not!
You may try with a AjaxFormComponentUpdatingBehavior instead.
changed.add(new AjaxFormComponentUpdatingBehavior("myevent") {...});
and in JavaScript:
function change(){
var change = document.forms[0].changed.value;
if(change != true) {
document.forms[0].changed.value = true;
document.forms[0].changed.myevent();
}
}
}
