delay tmux send-keys in vim function

I have a shell script (lets name it a.sh) where I run a certain command. At some point this command needs user input.

I have setup a vim key binding where I run a.sh in a tmux session. 

function! CreateTmux()
    !tmux has-session -t mysession || tmux new-session -d -s mysession
    !tmux send-keys -t mysession 'a.sh' Enter
    " This should be delayed by a few seconds
    !tmux send-keys -t mysession 'my choice' Enter
endfunction

nnoremap <F9> :call CreateTmux()<CR>

I would like to make a delayed send-keys through tmux to the session to input my choice for the prompt as well. Here is my code.

The limitations:
1. I hope to avoid blocking commands in vim so that I can continue working.
2. I can not edit a.sh so I can't make it pass without the prompt.
3. I don't have vim 8 and can't get it on the server that I am working on.

You could try running the last tmux line in the background with a shell sleep. Replace the last line of the function with

!(sleep 4 && tmux send-keys -t mysession 'my choice' Enter)&

You would only need the () if you want to replace the && by ; for example.
