Ionic Angular - Resetting scope variables

I have a flow of few pages/views starting from first page to last page. This is pretty much based on the Ionic tutorial.

I update a factory "Info" with some data as I proceed with the flow. In the final page, after displaying the "summary info" to the user, I use $state.go('firstPage') to navigate back to the first page.

When I make a different selection in the first page this time, it doesn't seem to take effect in the view.

I tried the suggestion from here but that didn't help me. I tried resetting the variables again, but that doesn't help either.

angular.module('my.services', [])
    .factory("Info", function(){
        // All user data
        var infoData = {
            type: "",
            level: 0
        };
    var originalInfoData = angular.copy(infoData);
    // Reset data
    infoData.resetUserDetails = function() {
        userData = angular.copy(originalInfoData);
    };

Final Page Controller

$scope.finish = function() {
    UseInfo.resetUserDetails();
    $state.go('firstPage');
}

This takes me back to first page but even though I select something different this time, the pages seem to remember what I did in my first run.

The question is - how do I clear things up so the user can do something else after getting back to the first page without remembering previous selections.
