Event edit not opening in month view

Hi guys! I have a problem. When I am in month view and click on an existing event, the create form displays instead of edit. Can you help me please? Thank you. Below is my code of init_scheduler();

function initScheduler() {
        dhtmlx.image_path = '<?php echo Yii::app()->baseUrl; ?>/imgs/';
        /* Scheduler */
        scheduler.config.multi_day = true;
        scheduler.config.xml_date = "%Y-%m-%d %H:%i";
        scheduler.templates.event_class = function(start, end, event) {
            if (start < (new Date())) //if date in past
                return "past_event"; //then set special css class for it
        }
        scheduler.config.drag_create = true;
        scheduler.config.event_duration = 60;
        scheduler.config.details_on_create = true;
        scheduler.config.details_on_dblclick = true;
        
        scheduler.config.cascade_event_display = true; // enable rendering, default value = false
        scheduler.config.cascade_event_count = 4; // how many events events will be displayed in cascade style (max), default value = 4
        scheduler.config.cascade_event_margin = 20; // margin between events, default value = 30
        
        scheduler.xy.menu_width = 0;
        scheduler.config.show_loading = true;
        scheduler.config.first_hour = 6;
        scheduler.config.last_hour = scheduler.config.first_hour + 24;
        scheduler.config.mark_now = true;
        scheduler.init('scheduler', null, "week");
						
						
						
		
        scheduler.attachEvent("onViewChange", function (mode , date){
            //any custom logic here
            $(".dhx_scale_hour").each(function(){
                k=greek_hour($(this).html());
                $(this).html(k);
            });				
            colorize_tasks();
        });
		  
		  
        scheduler.attachEvent("onXLE", function (){
            colorize_tasks();
        });
		
        scheduler.attachEvent("onEventAdded", function (){
            colorize_tasks();
        });
		
        scheduler.attachEvent("onEventChanged", function (){
            colorize_tasks();
        });
		
        scheduler.attachEvent("onEventSave", function (){
            colorize_tasks();
        });

        scheduler.load('<?php echo Yii::app()->request->baseUrl; ?>/site/getData');
        scheduler.config.dblclick_create;	


        scheduler.attachEvent("onClick", function(event_id, native_event_object) {
            var ev = scheduler.getEvent(event_id);

			openLightbox('dialog', '<?php echo Yii::app()->baseUrl; ?>/tasks/update/id/' + event_id,  ev.text, 950);
            colorize_tasks();
            return false;
        });

                       
        scheduler.attachEvent("onEventChanged", function(event_id, event_object) {
            $.ajax({
                type: 'GET',
                url: '<?php echo Yii::app()->baseUrl; ?>/tasks/updateEventTime/?id=' + event_id + '&snew=' + format(event_object.start_date) + '&enew=' + format(event_object.end_date) + '',
                success: function(){
                    colorize_tasks();
                    window.top.$("#notifbox").load('<?php echo Yii::app()->request->baseUrl; ?>/site/notifications');
					
                }
            });
			
        });
						
        $('#chkbox').live('click', function() {
            scheduler.detachAllEvents();
            //console.log('Ok!');
            return false;
        });
                    
        scheduler.showLightbox = function(id) {
            evopen = scheduler.getEvent(id);

            var lurl = null;
                       
            if (id > 1000000) {
                lurl = '<?php echo Yii::app()->baseUrl; ?>/tasks/create';
            } else {
                lurl = '<?php echo Yii::app()->baseUrl; ?>/tasks/update/id/' + id;
            }
            id > 1000000 ? scheduler.deleteEvent(id) : true;
			
			openLightbox('dialog', lurl,  'Νέα Καταχώρηση', 950);
        }
						
    }

In month view - there is no inline-edit functionality, only popup form is available.
For other modes ( day, week ) you need to have

scheduler.config.details_on_dblclick = false;

Correct! I don’t want inline edit… I want to open my custom pop-up. Can you help me please on how i can do it? Thank you
