$cordovaSocialSharing.shareViaEmail not working in $ionicPopup 'onTap;

I’m trying to use the shareViaEmail method from a button on an $ionicPopup. For some reason it is not working on iOS. It works perfectly fine on Android though. I can get console logs when the button is clicked but, the email app is never triggered to open. Here is the code I’m using for that section:

function ($ionicPopup, $cordovaSocialSharing, $cordovaDevice, $http, $timeout) {
            var _getDeviceData = function() {
                var deviceData = $cordovaDevice.getDevice();
                if(deviceData !== 'undefined' || deviceData !== null) {
                    return '\n \n \n --- Please enter your message above --- \n Platform: ' + deviceData.platform + '\n OS Version: ' + deviceData.version + '\n Cordova Version: ' + deviceData.cordova + '\n Device Model: ' + deviceData.model;
                } else {
                    return 'No device data was available.';
                }
            };

            var _openEmailShare = function(shareMessage) {
                if (shareMessage && window.plugins && window.plugins.socialsharing) {
                    $cordovaSocialSharing.shareViaEmail(shareMessage, 'Support Request', ['support@someEmail.com'], [], [], null)
                    .success(function(success) {
                        console.log('success!')
                    }).error(function(err) {
                        console.log(err);
                    });
                } else {
                    console.log('email share was not available.')
                }
            };

            var _buildModal = function(faqs, _scope) {
                // if the data comes back successfully, build modal
                var faqModal = $ionicPopup.show({
                    title: 'FAQs',
                    template: '<div ng-repeat="faq in faqs" class="faq-container"><h3 class="faq-question">{{faq.question}}</h3> {{faq.answer}}</div>',
                    scope: _scope,
                    buttons: [
                        {
                            text: 'Close',
                            type: "button white close-modal full-width padding-top padding-right"
                        },
                                            {
                            text: 'Contact Support',
                            type: "button green close-modal full-width padding-top",
                            onTap: function (e) {
                                e.preventDefault();
                                console.log('after preventDefault')

                                // THIS IS THE LINE THAT IS NOT FIRING
                                _openEmailShare(_getDeviceData());
                            }
                        }
                    ]
                });
            }; // end _buildModal

            // Show FAQ popup
            this.showFAQModal = function(_scope) {
                $http.get('http://www.somesite.json')
                    .success(function(response) {
                        _scope.faqs = response.faqs;
                    }).error(function(error, status) {
                        _scope.faqs = [{ question: 'OHNO! Something went wrong, please try again.'}];
                    });

                _buildModal(_scope.faqs, _scope);
            };
        }]);

Any idea why this wouldn’t work on iOS?
