Hi klogube,
If you want to call method in backingbean from javaScript you should use both clientListener And serverListener as:
1- Add clientListener inside your inputText as :
<af:clientListener type="KeyUp" method="keyUp"/>2- write javaScript function as :
<af:resource type="javascript">
    function keyUp(event) {
       var source = event.getSource();
       AdfCustomEvent.queue(source,"callServerListener", {}, false);
</af:resource>3-Add serverListener inside your inputText as :
<af:serverListener type="callServerListener" method="#{backingBeanScope.txnBean4.keyUpMethod}"/>Your InputText will be like:
<af:inputText label="Label 1" id="it1">
      <af:clientListener type="KeyUp" method="keyUp"/>             
      <af:serverListener type="callServerListener" method="#{backingBeanScope.txnBean4.keyUpMethod}"/>
</af:inputText>4- The java method:
public void keyUpMethod(ClientEvent event){
// do whatever u want
