        Adds `rest_framework.response.Response` with two parametrs
        to initial function.
            The first one is data of initial response.
            The second one is the path to template.
            This path can be described in View class attributes.
            If it is not path calculates like this:
                /<app_name>/<model_name>/<class_name>.html.djt

        @param function is a method of View class,
                        which we want to decorate.
