Hi guys,
I have an action column item and I want create a click event in my controller. I know there is a handler event in the action column itself. But I really need to reference in my controller file. I can't find any id/itemid property for action column item. So how how can a refer this element in the controller.

Please help me. here is my code

Code:
.........some other grid items ..........
     {
            xtype: 'actioncolumn',
            id: 'acViewCashDetails',
            width: 50,
            align: 'center',
            items: [{
            getClass: function(v, metadata, r, rowIndex, colIndex, store) {
                         if(r.get('referral_count')>0){
                                 this.items[0].tooltip='Click to view the details.';
                                 return 'view';    
                               }else{
                                    return '';
                                }
                        },
                            handler: function(view, rowIndex, colIndex, item, e) {
                                //some codes here. then it will work but, i already have a function in controller
                               // and I really want to use that function or just want create another in controller
                            }
                        }
                    ]
                }

........some other grid items .......
