Answer 1

Use a promise something like this...

    $scope.voteCheck = function(email, id) {
        var deffered = $q.defer();
        $http.get('ajax/voters.php?id='+item.ID+'&email='+email, {
        }).success(function(data) {
            deffered.resolve(data);
        });
        return deffered.promise;
    };

Then call something like this...

var votePromise = $scope.voteCheck($item.ID, email);
        votePromise.then(function (data) {
                return(data === "CanVote");
})
};
