^ i think this is clearer if not bound, i.e.

in .h:

   private:
    // Called when |error_ui_util::HandleRequestFileSource| succeeds.
    void OnFileSourceHandled(const base::DictionaryValue& files);

in .cc, call site

    error_ui_util::HandleRequestFileSource(...
        base::Bind(&ExtensionErrorHandler::OnFiledSourceHandled));

in .cc, implementation

  ExtensionErrorHandler::OnFiledSourceHandled(
      const base::DictionaryValue& files) {
    web_ui()->CallJavascriptFunction(
        "extensions.ExtensionErrorOverlay.requestFileSourceResponse", files);
  }

what about this?
