Formly does not process PATTERN validation messages

[sarunasBaltuonis]

Followed this example http://docs.angular-formly.com/docs/formlyvalidationmessages

app.run.js:

fvm.addTemplateOptionValueMessage('pattern', 'passwordPatternMessage', '', 'IS very invalid',  'Invalid Input');

form field:

key: 'newPassword',
				name: 'newPassword',
				type: 'input',
				templateOptions: {
					type: 'password',
					label: 'new password',
					required: true,
					minlength: 8,
					maxlength: 40,
					pattern: PASSWORD_REGEXP,
					passwordPatternMessage: '"Password should be 8 symbols..."'
				},

Yet in error messages I get

ab8askAlj213 is invalid

All other validator messages work well.
