Undefined local variable or method `smart_listing_resource'

[Kani999]

I want to use in-place editing for nested resource request_comments in project_requests show.

resources :project_requests do
    resources :request_comments, except: :index
end

When I set up everything and calls CREATE action, I get an error

Undefined local variable or method `smart_listing_resource'

app/controllers/project_requests_controller.rb

def show
...
    request_comments = @project_request.request_comments
    @request_comments = smart_listing_create(:request_comments, request_comments, partial: "request_comments/list")

What am I doing wrong?
When I try to use in-place editing on a resource itself (not nested) everything works OK. But with nested resource, I am not able to configure it right,
