Does not detect file changes on vagrant synced_folder

[falsandtru]

Official tsc compiler detect file changes when I use watch option.
But this compiler does not detect on guest machine when I change files on host machine.

Windows7 64bit
VirtualBox 4.3.28
Vagrant 1.7.2
Box chef/centos-7.1

typescript 1.5.0-beta
grunt-typescript 0.6.2

英語力が怪しいかと思うのでできれば日本語で対応していただけると助かります。

I found a my solution here: Unitech/pm2#931

I simply added usePolling: true to the watcher.js module.
