I think you have a basic misunderstanding of how erb templates work.
Anything in <% or <%= tags is evaluated when the template is rendered
- that is what rendering an erb template means. Furthermore, an
onclick options can only be a chunk of javascript.
As Matt says, you need to write a controller action that your form is
submitted to. Furthermore, be careful of the data you receive - if the
example you posted worked it would allow a user to run arbitrary shell
commands on your server.
