Validation Result Is Ignored

[jdaudier]

With these changes, we can now refuse to add an item unless it passes validation. We could also display error messages if validation fails by binding the invalid event in modelEvents. You can see how we've set our fields to blank fields on the model and also in the ui hash. If we start having more and more fields, you can see how this would quickly become unmanageable. Surely we can just clear the form when the model is cleared?

Validation Result Is Ignored

You provided the validation function in model, but in driver.js, you still add the model anyway, regardless of the validation outcome. I think you should wrap the last 2 lines inside onAddTodoItem() inside an if statement, such as if (this.model.validationError === null)
