you don't know which pad the demuxer created triggered the callback.
you have to check the caps of this pad to know whether it is the audio
or the video one.

and as a general remark, check the return values from functions that
have one (such as gst_pad_link() for instance), that will help you *a
lot* to spot your problems...
