Callbacks for edittext not working

Dear all,

I want to do something with the content of an edittext area - namely for onClick and for onDoubleClick. As you might know, these events are not triggered in edittext - but for example in a listbox. Hence I try to set up specific event handlers. But nothing happens when clicking/double clicking on the edit field.

→ What is missed here?

/*  on(Double)Click.jsx ====== UTF-8 ====================================
              check possibilites to act on an edittext click/doubleclick
Comment       There is no onClick (and no onDoubleClick) for edittext
              Hence appropriate event listeners must be defined
              See JavaScript Tools Guide for the eventName in 
              controlObj.addEventListener (eventName, handler[, capturePhase]);
