Email validation issue in angularjs [duplicate]

I have a form input field with type email in AngularJS. When I try to put user@something.partners then it doesn't allow.

I have checked the regex and it is

var EMAIL_REGEXP = /^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/;

Any help is highly appreciated. Thanks in advance.
