Passing $ionicModal into `this` on a service? :C

Having some issues passing $ionicModal into a variable to be used in my service.

angular.module(‘myModule’, [‘ionic’]).service(‘myService’, function($q, $ionicModal) {
this.modal = null;

this.init = function() {
    $ionicModal.fromTemplateUrl('my-modal.html').then(function(modal) {
        this.modal = modal;

this.setup = function() {;


The code should work, but unfortunately it does not, shows error:

 Cannot read property 'show' of null

Strangely, if I am to just use in the first promise it will display, but then I have no way to close it later. Help?

EDIT: I should add that I have a workaround with this issue (If anyone runs into it and a fix isn’t posted). Take your HTML file over to and then uncheck the “Remove attribute quotes” box and click “minify”. Switch over to use $ionicModal.fromTemplate(string) and it will work fine in your service.
