I want Enter Key not to submit a form. I did this first.

```js
  $("#send_c").keypress(function(e) {
    if (e.which == 13) {
      e.preventDefault();
      return false;
    }
  });
```

But the button and Enter key work the same. Nothing happens or submitted even by the Enter key. My second try is this.

```html
<%=form_for [@article, @article.comments.build], remote: true, :onsubmit=>"return false;" do |f| %>
  <%=f.text_field :body, id: "c_i"%>
  <%=f.button :submit, id: "send_c"%>
<%end%>
```

This did not work. The form is submitted both by Enter key and submit button.

What could be wrong?
