Positions of UI Elements under Vertical Layout Group

Ok,
I have a canvas in world space. And i have a ui element with Vertical layout group on it.
now there are 5 Buttons under the vertical layout.

Now if i access their position using RectTransform.position, all buttons have same position values which is lower left corner of the vertical layout group! Is this a bug or am i doing something wrong?

Please help, Thank you!
