Bibliography In beamer and Table of Contents

When i am running the code and generating pdf (from tools to commands to biber in Texstudio), the references page is not giving numeric numbering to the references, instead a small box if forming.

Also how to add table of content in the beamer. Do i need to add section/subsection command for generating pdf or the frame title will do its job.
