Magento 2: data-mage-init validation not working

if data-mage-init validation not working on checkout page or any other page then instead of using data-mage-init use following code on that element:

Instead of this: 

<form data-mage-init='{"validation":{}}'>

Use this code:

<form data-bind="mageInit: {'validation': {}}">

it will definitely work.
