Ionic Firebase Links

I´m a very very new on ionic and FrontEnd Developing, and i have a question that may sound silly, but there it is;

I have an app that fetches data from firebase, i want to add a link to a button, and it must link to some info saved on firebase {{feed.moreInfo}}
I´ve tried classic html

<a href="{{feed.moreInfo}}"><div>MORE INFO</div></a>

and it works, but i´ve read that´s not good practice on ionic,
Could you give me some links or examples of how to do it?
Thanks in advance!
