Changing textfield between enabled and disabled

Question

I have 2 radio buttons and 1 TextField and now I want to do changing between enabled and disabled TextField. If radioFindText is selected then TextField must be enabled otherwise it must be disabled. I was trying with such code but it doesn't work and I am running out of possible solutions. It seems that method onSelectionChanged is never called, why?

EDIT Ok I finally found a solution and maybe it is obvious for ppl who work in wicket for a while but for my first project I found it difficult to solve it. Here is the working code.

    searchedText.setOutputMarkupId(true);
    RadioGroup group = new RadioGroup("group", selected);
    group.setOutputMarkupId(true);
    Radio radioErrors = new Radio("errors", new Model<String>("ERRORS"));
    Radio radioFindText = new Radio("text", new Model<String>("Find text"));
    group.add(radioFindText.add(new AjaxEventBehavior("onchange") {
        @Override
        protected void onEvent(AjaxRequestTarget art) {
            searchedText.setEnabled(true);
            art.add(searchedText);
        }
    }));
    group.add(radioErrors.add(new AjaxEventBehavior(("onchange")) {
        @Override
        protected void onEvent(AjaxRequestTarget art) {
            searchedText.setEnabled(false);
            art.add(searchedText);
        }
    }));
    group.add(searchedText);
    form.add(group);

Answer 1

its been a long time, since i coded wicket, but maybe you could use this:

radioGroup.add(new AjaxFormSubmitBehavior("onchange") {public void onSubmit(AjaxRequestTarget target) {...}}

i guess you need this to get "onchange" - notifications
