keybind is not working when open multiple buffers (nvchad)

[phamngocquy]

I'm using nvchad + tabby-nvim and realize a problem while open multiple buffers:
open nvim with first buffer opened:

when open new buffer:

After checking around I see that, the function tabby#inline_completion#keybindings#Setup is just initilized when open fisrt buffer.

function! tabby#inline_completion#Install()
  call tabby#inline_completion#events#Install()
  call tabby#inline_completion#keybindings#Setup()
  call tabby#inline_completion#virtual_text#Setup()
endfunction

sulution here is create an autocmd

function! tabby#inline_completion#Setup()
  augroup tabby_inline_completion_events
    autocmd!
    autocmd User tabby_lsp_on_buffer_attached call tabby#inline_completion#Install()
  augroup end
  autocmd BufNewFile,BufRead * call tabby#inline_completion#keybindings#Setup()
endfunction
