How can I insert bootstrap-autohindingnavbar into ember application?

I'm new to ember, and I've been searching a lot for doing that navbar-fixed-top hides when scrolling in an ember app. The code is:

$(".navbar-fixed-top").autoHidingNavbar()

that's all. It seems easy... but when it comes to where put it and how deal with this simple expression, I found no clear answer.
