Synced folder in vagrant is not syncing in realtime

I am setting up a synced folder in a vagrant machine like shown in cmd dump below and expect that whenever I update the files in this folder on the host machine the updates will be reflected inside guest machine too, however this is not happening.

Here is the dump and evidence of it not happening (I create a sample file and modify it by changing text in in it from test1 to test2):

mypc:~ user$ cd Projects/synctest/
mypc:synctest user$ ls
Vagrantfile
mypc:synctest user$ cat Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  # always use Vagrants insecure key
  config.ssh.insert_key = false

  # Setup box
  config.vm.box = "coreos-stable"

  # Setup shared folder
  config.vm.synced_folder ".", "/vagrant"

  # Setup memory usage
  config.vm.provider "virtualbox" do |v|
    v.memory = 2048
  end

  # Define `dev` vm
  config.vm.define :dev do |dev|
  end

  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
  end

end
mypc:synctest user$ echo "test1" > test.txt
mypc:synctest user$ cat test.txt
test1
mypc:synctest user$ vagrant up

core@localhost /vagrant $ cat test.txt
hi from guest machine
core@localhost /vagrant $ exit
logout

mypc:synctest user$ cat test.txt
test2
mypc:synctest user$

Is it even supposed to sync realtime? If yes, why is not syncing?

Edit: OS X 10.8.5, VirtualBox, coreos box.

In your Vagrantfile the synced folder type is default vboxsf, however, in the vagrant up stdout, it is showing rsync type, I think you need to fix it in the config file.

Assume that you are using rsync type, you should have the following in your Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.synced_folder ".", "/vagrant", type: "rsync",
    rsync__exclude: ".git/"
end

NOTE: By default, rsync__auto is set to true, which means rsync-auto will watch and automatically sync this folder.

Run vagrant rsync-auto and the directory should be in sync between host and guest.

Refer to vagrant docs for more information.
