getterSetter: boolean value which determines whether or not to treat functions bound to ngModel as getters/setters to have greater control over your model.
allowInvalid: boolean value which indicateds that the model can be set with values that did not validate correctly instead of the default behavior of setting the model to undefined.
For example input type="email".
