The code has been chaged from :'data-confirm' to :data, modify the documentation.

Thanks for the pull request @teeceepee! 😄 I don't know if this is the best change though. The option is method: not method: :delete. If I was a brand new Rails developer reading this I'd think the only counterpart to method: is :delete, you know what I mean?

I do think an example could be good here though, but it should be below the main explanation. Can you update your pull request? Thanks!

@eileencodes Just change :'data-confirm' to :data, OK?

@teeceepee ah I see. I'm sorry I didn't look at the surrounding documentation. Your change does make sense in that context so no need to do the changes I asked for.

But while we're editing this paragraph can you change the last 2 sentences to say:

This is done via the JavaScript file jquery_ujs which is automatically included in your application's layout (app/views/layouts/application.html.erb) when you generated the application. Without this file, the confirmation dialog box won't appear.

It just changed "into" to "in" and "wouldn't" to "won't" for a better sounding sentence. Thank you!

@eileencodes I have changed the guide as what you said.
