How to make NerdTree auto refresh if I create a new file from vim terminal

[hungpham3112]

It seems that nerdtree doesn't have the ability to autorefreshing. I open a Vim's terminal and nerd tree. When I create a new file with touch newfile, I observe that Nerdtree doesn't show the new file, I have to manually type r or :NerdTreeRefreshRoot. How do I automatically refresh nerdtree structure when a new file is created?
