Can't destroy CKEditor instances

Hi,

I have a little problem here: I cannot destroy any CKEditor instances. The code is rather simple:

this.rbCKEditor.on('destroy', function() {
  log('destroying');
});

log(this.rbCKEditor);
this.rbCKEditor.destroy();
log(this.rbCKEditor);

But the result on the console is

Object
destroying
Object

it should be

Object
destroying
undefined

Also I cannot create any other instances of CKEditor any more that have the same name as the one I tried to destroy which let's me come to the conclusion that the instance is not being properly destroyed. But also, I have no idea why this doesn't work.

You guys have any tips?

Thanks
Lukas
