With the right click on the record i get a copy of it, but how to call the edit form when performing this process?

odoo.define('contextmenu.web', function (require) {
"use strict";

var ListController = require('web.ListController');
var ListRenderer = require('web.ListRenderer');

    ListController.include({
         custom_events: _.extend({}, ListController.prototype.custom_events, {
           duplicate_record: '_onDuplicateRecord',
         }),

         _onDuplicateRecord: function(event) {
            event.stopPropagation();
            var self = this;
            this.handle = event.data.id;
            this.model.duplicateRecord(this.handle);
         },
    });

    ListRenderer.include({
       events: _.extend({}, ListRenderer.prototype.events, {
           'contextmenu tbody tr': '_onContextMenu',
        }),

        _onContextMenu: function(event) {
            var target = event.target;
            while (target.tagName !== 'TR') {
                target = target.parentNode;
            }
            if (target.className === 'o_data_row') {
                var id = $(event.currentTarget).data('id');
                if (id) {
                    this.trigger_up('duplicate_record', { id: id, target: target });
                }
            }
        },
    });

});

Should I use this option?

this.model.duplicateRecord(this.handle)
    .then(function (handle) {
        self.handle = handle;
        self._updateEnv();
        self._setMode('edit');
    });

If yes, why this problem occurs?
