title: Using decorated helper methods in same engine
body: <p>I'm decorating a couple of helper methods in another engine:</p>
  
  <pre><code>Backend::PathHelper.module_eval do
  
    def spent_appable_points_path(paramz = {})
      send("spent_#{appable_type}_points_path", appable, paramz)
    end      
  
    def earned_appable_points_path(paramz = {})
      send("earned_#{appable_type}_points_path", appable, paramz)
    end
  
  end
  </code></pre>
  
  <p>Using these two methods inside my views in the Backend engine works fine. But when I try to use these two methods in the same engine I am decorating it in, they are not available. </p>
  
  <pre><code>Backend::PathHelper.public_instance_methods # doesn't return them
  </code></pre>
  
  <p>What would the proper DRY way to be able to use these two methods in the same engine?</p>
