add :onchange => "readURL(this)" to input file on simple_form

Question

I have a problem with this:

I want add :onchange => "readURL(this)" to my:

<%= f.input :image, :as => :file, :onchange => "readURL(this)" %>

I have tried with:

<%= f.input :image, :as => :file, :html => {:onchange =>
"readURL(this)"} %>

but I can not see the onchange="readURL(this)" in html code.

How can I fix this problem?

Thank you again :D.
