parent child relation btwn gammeobject and a ui canvas and ui text positioning problem

I am making enemy kill score display i.e.,when i kill an enemy scores displays above it.For this i stored my ui text and canvas as a child of a empty game object and instantiating this empty game object at the position where my enemy is destroyed

My problem is i can see my enemy death score at a single point in my game its not according to enemy death position.

plz help me in this issue

make sure the text displaying the enemy kill score is a child of the canvas and that the text is within the boundaries of the canvas
,Make sure that the text displaying the information is below the canvas…And if it is make sure its within the boundaries of the canvas
