Vim assumes that you want to determine the file type when a file is
opened or a new buffer is created, i.e., before you start viewing or
editing, not when you write the file. In most cases, by the time
you write a file you've either already set the file type or you
don't care.

The easiest way to set the file type after writing a file is to
simply edit it again,

If you really want to automate this, you could put an autocommand
like this in your ~/.vimrc:

au BufWrite * if &ft == '' | filetype detect | fi
