ActionController::UnknownFormat when using respond_to do |format|

I am using jquery slider ui and rails 4. I am trying to implement a
price
slider for my product page. However, i have run into a problem. I have
tried to search around but i cant seems to find a solution that helps.
Hope
someone could help me as I am quite new to ruby on rails. Thanks.

Here are my code

products_controller.rb

respond_to do |format|
format.js do
render :update do |page|
page.replace_html ‘x_product_list’, :partial =>
‘products/products_list’, :locals => { :product => @product }

with this error:
