Update Text on Gameobject initiated from script from other Gameobject

Dear Unity,

I am developing for the HoloLens and I Made an object that follows me around. This Gameobject is actually an UI Canvas with text in it which I set like this (Just like in the MS example):

  /// <summary>
 /// The object to tag along set in the unity editor
 /// </summary>
 public GameObject ObjectToTagAlong;

 /// <summary>
 /// The instantiated object to tag along that follows you around.
 /// </summary>
 private GameObject instantiatedObjectToTagAlong;

  this.instantiatedObjectToTagAlong = GameObject.Instantiate(this.ObjectToTagAlong);

this instantiatedObject tags along just fine but now I want to update the Text on instantiatedObjectToTagAlong but have no idea how to do this. (I can very easily update the text on the 1st object but i want to do it this way)

How can I update the text from script real-time on an object that I made from another object?

Thank you already,
