How to pass more than one param into state.go?

Hi guys, please give me you advice about the best way to pass multiple parameters into $stat.go servise.
I have this code:

                'profileTypeTitle': $scope.profiletypeOptions.selectedOption.title,
                 'userEmail': $scope.registerData['AccountRegisterForm[email]']

But in console I can see this: {profileTypeTitle: “My title”}
I would like to see something like this: {profileTypeTitle: “My title”, ‘userEmail’: $scope.registerData[‘AccountRegisterForm[email]’]}
Is it possible and how?
