Wiselinks and simple navigation do not cooperate

I use the wiselinks and the simple navigation gems. If I click on menu item with data-push="true", the active class is not switched.

Undefined method render_navigation in using Simple Navigation gem Rails 4.2

I have been using Rails 4.2.0 beta and using SImple navigation

i have added

gem 'simple-navigation'

in my gemfile and did

bundle install

And added a file under config/initializers/navigation.rb which has

require 'simple-navigation' SimpleNavigation.config_file_path = File.join(Rails.root, 'config', 'navigations')

And i have a file article_navigation.rb which has

SimpleNavigation::Configuration.run do |navigation|
navigation.renderer = SimpleNavigation::Renderer::List
navigation.autogenerate_item_ids = false
navigation.selected_class = 'active'

navigation.items do |primary| primary.item :new_article, 'Post an Article', "#" primary.dom_class = 'nav' end end

In my View file articles/index.html.slim

I have tried to use = render_navigation(context: :article)

which throws

NoMethodError (undefined method `render_navigation' for

<#:0x007f9cdc95ab98>):

Help me in fixing this.
