Currently in a partial, I have the following:

\<% @blogs.each do |blog| %\>  
\<% fields\_for “#{Time.now.to\_i}”, blog do |f| %\>

How do I update the #{Time.now.to\_i} every time the user clicks?

Currently, the Time only gets set whenever the page is loaded, is  
there a way to replace this using javascript?  
I’ve poured through Nest Form railscasts, as it solves a similar  
problem, but I can’t seem to adapt it to my needs.  
Honestly, I don’t even need to use Time, just a variable that  
increments so that the form’s id’s are different and Time just seemed  
like a logical choice.

Any help on this is greatly appreciated.
