Event listener for specific property value change


how can i create even listener using eventBus to listen the changes in panel properties specific control e.g . changes in TextboxA

I see below one is refer to change in all panel properties elements

eventBus.on('elements.changed', function(e) {

    var current = self._current;
    var element = current && current.element;
    if (element) {
      if (e.elements.indexOf(element) !== -1) {


You cannot listen to specific property changes right now.
