I've answered a similar question here AngularJS - How to trigger submit in a nested form

Basically, you can trigger validation by firing $validate event

isFormValid = function($scope, ngForm) {
    $scope.$broadcast('$validate');
    if(! ngForm.$invalid) {
      return true;
}

For working code example & a small utility method which is helpful in showing validation messages, see answer in the above link.
