destroyRecord() does not trigger model listeners (Ember Beta)

Ember Version: 1.10.0-beta.3, Ember Data: 1.0.0-beta.12

I have several computed properties with .property('model'). But when I do destroyRecord() in a controller action the property function does not fire. I can force that by notifyPropertyChange() and then function indeed fires, but then template doesnt get rerendered for some reason.

Whole action code looks like this:

cleanSpot: function(id){
                        var id = this.get('clickedId');
                        var _this = this;

                        this.store.find('spot', id).then(function(spot){

                                return spot.destroyRecord();

                        })
                        .then(function(){
                                // _this.notifyPropertyChange('model');
                                var popupController = _this.get('controllers.popup');
                                popupController.set('isVisible',false);
                        });
},

Interesting is, that this similar action to add a record, works just fine:

addSpot: function(style){
                        //WARNING: Security
                        var _this = this;
                        var data = {
                                x: this.get('hoveredX'),
                                y: this.get('hoveredY'),
                                city: this.get('city'),
                                style: style
                        };
                        this.store.createRecord('spot',data).save().then(function(){

                        }).catch(function(){
                                //rollback?
                        });
                        
},

I started to get these issues after I updated to Ember Beta, but I guess its more likely that I am doing something wrong than that it is a bug.
