knockoutjs - $evalasync (angularjs) equivalent

trying to have a function get executed once in a custom binding handler to resize some divs based on their contents. I am able to easily do this in angularjs but I am trying to find something that behaves like $evalAsync for knockout.

http://docs.angularjs.org/api/ng.$rootScope.Scope

Is there a feature like this I can hook into?

it's for koGrid 2.0 auto-widths. Right now it only works on single page apps because I am hooking into document.ready :(

Maybe the afterRender callback can be used?
