CKeditor - focus won't work

I have troubles with getting the cursor of CKEditor in my ckeditor box...

I have 2 instances, same shared space en following code won't trigger the cursor to be visible:

- $('#page_' + publisher.activePageID + '_container').focus();
- config.startupFocus = true;

Somebody with an idea of how to get the CKEditor focus aka cusor active on the instance that you want?
