Problem

Why doesn't JavaScript work when I redirect from Rails Controller?

How do I modify it so that JavaScript works?

Code

sessions_controller.rb (Redirect by Create action)

class SessionsController < ApplicationController
  ...

  def create
      ...
      redirect_to root_path
  end

  ...
end

rails routes

% rails routes | head
Prefix Verb   URI Pattern Controller#Action
root   GET    /           shops#index

shops_controller.rb

class ShopsController < ApplicationController
  def index
    ...
  end

  ...
end

index.html.erb

...
  <%= render partial: "shops_sort_by_distance", locals: {area: area} %>
...

index.js (Not executed)

window.onload = () => {
    ...
    func();
};
