title: Why Particplesystem Position is wrong while attached to a GameObject?
body: <p>I'm working with unity 5(2D project).
  I attached a ParticleSystem to a GameObject(an UI Button). now i can see both of them but they are not in the same position.
  I move particplesystem manually and put both object in the same position .but when i move my object they will not move togothere... particlesystem will move lower and objects will have different positions.</p>
