I sorted it out by adding protect_from_forgery which does what authenticity_token in form does.
class EventController < ApplicationController
protect_from_forgery
def list
end
def details
end
def update
render :json => { :status => :ok, :message => 'Good Morning'}
end
end

This error is related to cross-site request forgery protection . Rails inserts an authenticity_token input inside your form to protect you against it. Run your application and then using Dev Tools (ex Chrome Dev Tools) inspect the page and verify that your form has the following input: (Note that the value attribute will be different)
<input name="authenticity_token" type="hidden" value="f755bb0ed134b76c432144748a6d4b7a7ddf2b71" />
Also make sure you are using POST method to send the form
