hexl-mode doesn't support adding or deleting characters, it only
supports replacing them.  E.g., hexl-insert-hex-char _replaces_ the
character at point with what you type.  So what you see is what this
mode is supposed to do: it is based on the assumption that the size of
the file you are editing shouldn't be changed.

If you want to create a file from scratch, why do you need hexl-mode?
You can type bytes in hex or octal using C-q.
