Help with rack-Recaptcha

[santoshkumar savadatti]

I am experimenting with recaptcha for rails 3.For that iam trying out a simple app. I'm using rack-recaptcha Plugin. I have followed all the steps as mentioned on the gem page.But, when i run the app, the reCaptcha always returns false.
Here's my view:

<[e-mail] do |c|%>
	<h1><%=c.value%></h1>
	<p id="fail" style="display:none">Incorrect recaptcha</p>
	<p id="para" style="display:none">Succesfully Incremented</p>
	<%=raw recaptcha_tag(:challenge)%>
	<%=button_to 'Increment',increment_path(:format=>:js,:id=>c.id),:remote=>true%>
	<%end%>

and Here's my controller:

include Rack::Recaptcha::Helpers
	def display
		@digits=Digit.all
	end
	
	def increment
		if recaptcha_valid?
		@digit= Digit.find(params[:id])
		@digit.increment!(:value)
		respond_to do |format|
			format.js
		end
	   else
	   	respond_to do |format|
			format.js {render 'fail.js.erb'}
		end
	end
	end

I haven't used the recaptcha gem, so I'm not in a position to suggest gotchas, etc, but I'd be happy to help suggest avenues for troubleshooting.

First up... what does your config look like?

[santoshkumar savadatti]

I added the following lines to my application.rb:

config.gem 'rack-recaptcha', :lib => 'rack/recaptcha'
    config.middleware.use Rack::Recaptcha, :public_key => 'My Public Key', :private_key => 'My Private Key'

and in my IndexHelper.rb (my controller name is Index) i added:

include Rack::Recaptcha::Helpers

and in the gemfile,

gem 'rack-recaptcha', :require => 'rack/recaptcha'

Are you able to make it work without Ajax? I.e. just using regular redirects?
