progress bar in ember js

I am looking for a progress bar kind of add-on for my ember app. Requirement is user goes through a setup process and in the end when user clicks submit, then I have to show him the complete progress with a loading bar indicating how much work is done.

I used ember-progress-bar but the problem is animation starts from 0 all the time whenever I update the percent value. Is there anything which we can use and is easily available? I can design my own but still wanted to confirm first if there is something which can be used.
