How to create an auto-refreshing variable in Ember?

I am still rather new to Ember and I am stuck on an idea that I would like to get done. I could do this in JQuery/Javascript, but I want to use some of the Ember features to get this properly done.

I am trying to create a live stock ticker, that would simply auto-refresh every few seconds with a value +50, -100, +1512, -25, etc.

I am mostly just stuck on how to get a variable that auto-refreshes per the allotted amount of time. Should I create a custom component?

Any tips would be appreciated, thanks
