c3_chart_internal_fn.observeInserted causes a memory leak

[thomasvanlankveld]

I'm building a backbone application using c3. When I move away from a view containing a c3 graph, a leak appears from window.setInterval(). I tried cleaning up using destroy(), but probably this doesn't access the interval set on window.
