Stop click event propagation in ionic frameworks $ionicActionSheet?

I'm using $ionicActionSheet and underneath it (before it's opened) there is textarea. When the user clicks the button in the $ionicActionSheet it also brings focus to the <textarea> below and opens the keyboard. Is there any way to stop the click propagation in the $ionicActionSheet?

    $ionicActionSheet.show({
        buttons: [{
            text: 'Camera'
        }, {
            text: 'Photo Library'
        }],
        destructiveText: 'Cancel',
        destructiveButtonClicked: function() {


            //
            // How do I get access to the click event?
            $event.stopPropagation();
            //
            //


            return true;
        },
        buttonClicked: function(index) {


            //
            // How do I get access to the click event?
            $event.stopPropagation();
            //
            //


            if(index == 0) {
                $scope.TakePicture("camera");
            } else {
                $scope.TakePicture("library");
            }
            return true;
        }
    });
