```coffeescript
      return unless keychord(e) is 'Backspace' or field.value
      $.globalEval 'Recaptcha.reload("t")'
```
translates to
```coffeescript
      if keychord(e) is 'Backspace' or field.value
        $.globalEval 'Recaptcha.reload("t")'
```
which will always reload `if field.value`, and we don't want that.
