destroy it after completion of work with model. example

keys: { 
          esc: function() { 
                     var r=confirm("Are you sure, you want to do this?");
                            if (r==true){
                                this.close(); 
                                this.destroy();//this you need to do
                                $('overlay').setStyle('display', 'none');
                            }else{}   
                        }
