NoMethodError in People#new
Showing /home/local/PENNYWISE/venkatab/Desktop/rails/dynalists/app/
views/people/_form.html.erb where line #26 raised:
undefined method `observe_field' for #<#<Class:0x007f511c403ed0>:
0x007f511c347cd0>Extracted source (around line #26):
23: <%= f.label :state_id, "state" %><br />24: <div id=

"update_state_div"} , :with => :person_country_id %>27: </div>28:
