+form submit() event is bound to jQ func **validateForm()**

+when the form is submitted, it calls jQ func **$.formUtils.validateInput**, which calls **validatorFunction** for the specific validation rule assigned to the input element

+if a validation fails, error messages are assigned and displayed as configured.
