Please see the documentation. You need to mapped.

    " <CR>: close popup and save indent.
    inoremap <silent> <CR> <C-r>=<SID>my_cr_function()<CR>
    function! s:my_cr_function()
      return neocomplcache#smart_close_popup() . "\<CR>"
      " For no inserting <CR> key.
      "return pumvisible() ? neocomplcache#close_popup() : "\<CR>"
    endfunction
    " <TAB>: completion.
    inoremap <expr><TAB>  pumvisible() ? "\<C-n>" : "\<TAB>"
