Validations are not working except first tab of wizard and data loss between tabs

Question

I am trying to use wizard with Primefaces (ViewScoped) . I created the page with 4 tabs. After navigating first tab, user reaches second tab and user enters some values to the input text fields at this second tab page. When the user goes the previous or next tab from second tab and comes back to this second tab all the entered values are lost except first tab. Also validations are not working except first tab.Is there a solution for this problem? Here is my html code:
