// OnPopulateMesh() was getting called before m_OutputText was updated in function UpdateQuadImage(), Due to this, m_HrefInfos.boxes where not getting created, which in further resulted into non clickable text. This is happening in Unity5.5.

So what i did is i assigned m_Text = GetOutputText(); directly in  OnPopulateMesh() function, which solved the problem.
