Plus (and i don't exactly remember) but i don't think it is stated the book is written in Khuzdul. In the movie it was written in Sindarin on one page then Khuzdul on the other. Even though it's not a canon source, it is a logical conclusion...

 Actually it was that way in Tolkiens mind too. Just checked.
