Sometimes you get struck in such cases where it seems no one in other million people faced.

ASP.NET 4.5 unobtrusive validation enabled by default if you just add a scriptmanager to the page client side validation won't work anymore if you update Jquery to greater version than 1.9+

<appSettings>
    <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

This will use "old style" non HTML5 validation and WILL work with ajax and JQuery 1.9

this may help someone else

Microsoft fixed their unobtrusive validation library to be compatible with jQuery 1.9+ about two weeks after 1.9 was released. Update the package through the Package Manager Console as described here: http://stackoverflow.com/a/15539422/680485 – ThatMatthew Feb 25 '16 at 16:02
