calling a function on bufenter,bufnew,bufread

I have the following in my .vimrc -- but the call to the function
isn't working. If I call the function manually after it opens, it
works fine. The filename is set to vimperator.txt. Do I have to do
something different to call a function in this way?

function! WW()
:set showtabline=0
:set noshowmode
:set laststatus=0
:set noruler
:set noshowcmd
:call VimWriteRoom()
endfunction

nnoremap WW :call WW()<CR>

au BufNewFile,BufEnter,BufRead vimperator.txt :call WW()<cr>
