Action is invalid after a rerender

Both the action and handler end up being undefined for some reason. This action fires fine in some situations, but when it's called on didReceiveAttrs in other situations it seems to do this.

The action is assigned in the index route, but defined in the parent route.

index:

{{some-component obj=obj onSetup=(route-action 'loadShare')}}

the onSetup is fired in didInsertElement and didReceiveAttrs if the component rerendered with a specific object again.

parent:

  actions: {
    loadShare() {
      this.controller.loadShare();
    },

Looks like getRoutes (called from getRouteWithAction) only returns the application and loading routes, so nothing is found.

Wrapping my action call in an event from google maps helped:

        google.maps.event.addListenerOnce(map, 'tilesloaded', bind(this, () => {
          if (this.isDestroyed || this.isDestroying) {
            return;
          }

          onSetup();
        }));

afterRender and next didn't work.
