ngMaterial with Ionic

I am trying to use ngMaterial with Ionic framework. I have added ngAria, ngMaterial using bower and also included the script files in the html also in the app.js module dependencies. But it is not working for me.
For example, I tried using md-button but it appears as below, it is nowhere near to what I wanted it to be. I also tried other things but all of them resulted in similar issues. Can anyone help me with this?
