bibliographies and siunitx in pandoc

Question

I'm using pandoc to convert my TeX file in a .docx file. The formatting, equations and images work very well, but I have some issues:

1. References to images don't show properly. They show only the name of the image file, not the number, neither in the caption nor inside the text.
2. The bibliography doesn't show; the numbers of the references papers ([1], [2] etc.) also don't show.
3. In the LaTeX file I'm using the siunitx package; pandoc doesn't convert syntax like \SI{5}{mm}.

Can anyone help me?
