    Default Answered: Reference instance function/variable inside a store refresh event

    I have a controller in which I initialize a store for my view. Now when the store is loaded, I want to apply a function to each record with the each method of the store, so I'm binding on refresh event (which is properly called), however, this does not point to the right scope and I don't this how to call a function of my controller singleton and reference a instance variable of my controller.
    Thanks for any pointer.
    Code:
    getMyStore:function () { // Method of my controller, loading the store from the launch method.
            return Ext.create('Ext.data.Store', {
                model:'My.model.Bean',
                sorters:'date',
                proxy:{
                    type:'ajax',
                    url:'app/resources/data/some_data.json',
                    reader:{
                        type:'json',
                        rootProperty:'root'
                    }
                },
                autoLoad:true,
                listeners:{
                    refresh: function(){
                        this.calcForEach(this); // This is the method of my controller
                        console.log('Store length : ' + store.getCount());
                    }
                }
            });
        }

  2. Code:
    listeners : {
        scope : this,
        refresh : function() {...} //scope is of this which should be the controller
    }

    The first argument in a refresh event is the store.

    I'm looking for a pointer to my controller, not to my store...
