Rails best_in_place gem not updating data

Question

I've looked everywhere for a solution to this, but all of the common solutions to this issue aren't working for me. Any help is greatly appreciated.

My problem is just that the rails best_in_place gem doesn't save any of my data after I make a change. It will allow me to type in the new change, but it won't update the database after I press enter (it also doesn't work if I refresh the page, which was the initial problem on the RailsCast for this gem).

Controller code:

def update
respond_to do |format|
  if @renter.update_attributes(renter_params)
    format.json { render json: @renter }
    flash[:success] = "Profile updated"
    redirect_to @renter
  else

    render 'edit'
  end

end

end

View page code

    <li><span class="content"><b>Name: </b><%= best_in_place @renter, :name %></span></li>  

Thanks in advance!

Edit: Adding renter_params from controller

def renter_params
    params.require(:renter).permit(:name, :email, :password, :password_confirmation)
end

(Note: I've never had any problems with renter_params per se, my updates always save OK in the database)

Edit: adding code from javascripts/application.js

//= require jquery
//= require best_in_place
//= require best_in_place.purr
//= require jquery_ujs
//= require jquery.purr
//= require bootstrap
//= require turbolinks
//= require_tree .

renters.js.coffee

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/
jQuery ->
    $('.best_in_place').best_in_place()

If you haven't yet, modify your gem as this:

gem 'best_in_place', github: 'bernat/best_in_place'

by simply doing gem 'best_in_place' didn't work for me.

if that doesn't work, as the documentation suggest, replace:

format.json { render json: @renter }

with:

format.json { respond_with_bip(@renter) }

respond_with_bip is a "utility method you should use in your controller in order to provide the response that is expected by the javascript side, using the :json format", says the documentation. I'm not sure how much this matters as my Rails 4 app is working without it.

Finally, if the update action is restricted to logged in users only, make sure you are logged in.
