How to specify custom --rulesdir for eslint in vim editor

I have installed syntastic plugin in vim and installed eslint in npm globally. Below is the snippet of my .vimrc for syntastic configuration:

set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*

let g:syntastic_javascript_checkers = ["eslint"]
let g:syntastic_always_populate_loc_list = 1
let g:syntastic_auto_loc_list = 1
let g:syntastic_check_on_open = 1
let g:syntastic_check_on_wq = 0

Here's the result when I run :SyntasticInfo javascript,

Syntastic version: 3.6.0-64 (Vim 704, CYGWIN_NT-6.3)
Info for filetype: javascript
Global mode: active
Filetype javascript is active
Available checker: eslint
Currently enabled checker: eslint

Assume I have following project structure, there're some custom rules activated in .eslintrc, and the definition of those rules are in .eslintrules dir:

xxx_project:
   |--.eslintrc
   |--.eslintrules
        |-- rule1.js
        |-- rule2.js
        |-- ...
   |-- src
        |-- abc.js

Everytime I run :SyntasticCheck on some source file, nothing happens. So I try running eslint against some js file directly in command line. There're some errors threw indicating cannot find definition of some custom rules.

So I think eslint has found the configuration file, but it doesn't know where the --rulesdir is.

Can someone help here? As far as I know, the --rulesdir option is only available in command line.

Edit:

function! ESLintArgs()
    let rules = findfile('.eslintrules', '.;')
    return rules != '' ? '--rulesdir ' . shellescape(fnamemodify(rules, ':p:h')) : ''
endfunction

autocmd FileType javascript let b:syntastic_javascript_eslint_args = ESLintArgs()

This tries to find a file named .eslintrules and sets --ruledir to its base directory.
