back button for form preview in rails

I have a problem while making a back button for form in rails. I have a dynamic form that looks like this: dynamic form

However, when I press 'preview' button, the page will redirect to another page. In this page, I have created button: 

<%= button_to 'Back to edit', 'javascript:history.go(-1);', {class:'btn btn-primary'} %>

It really back to previous form, but only 1 single form displayed returned form

Can anyone can help me???

You can do this follow as:

<%= link_to 'Back to edit', :back %>

Most browsers will cache the back action and therefore won't issue an HTTP request to your server. If you need to display fresh data, then use a redirect via javascript's window.location rather than relying on the history state.
