Method with Parameter jsf + output

How can I pass a parameter to a method and at the same time return the value of the method with output?

Example.

//Bean
public String getResposta(String ok){
    return ok;
}

//pagina

<h:outputLabel value="#{bean.resposta('RespostaParaRetornar')}">

How do I get the same effect from this syntax in jsf? or how do I make it work. NOTE: I do not want to pass the parameter in commandButton, I need it in outputText or outPutLabel.

Using this example syntax does not work.

JSF has a syntax error. and the page throws exception.javax.el.MethodNotFoundException:
