`this.options.listeners.onFormSubmit( valid, event, this );` is not the valid line.

These are:
```js
// if onFormSubmit returns (bool) false, form won't be submitted, even if valid
  var onFormSubmit = this.options.listeners.onFormSubmit( valid, event, this );
  if ('undefined' !== typeof onFormSubmit) {
    return onFormSubmit;
  }
```

That's why tests are failing
