Решил проблему сам изменил две функции:

function addrashetc (iddate)
                {
                               var popup = '#popup1';                              
                               $(popup).show();       

                               $.ajax({
                                               url: "/RL/modal/modaladdvichet.php",
                                               type: "POST",      
                                               data: { "iddate": iddate },
                                               cache: false,                                     
                                               success: function(response)
                                                   {
                  $("#news1").append(response); 
                  $("#datepicker").datepicker({ dateFormat: 'dd-mm-yy'});
}
                               });
                }

function plusvi(iddate){
                 var start = document.getElementById ('datepicker').value;
                       $.ajax({
                                               url: "/RL/modal/addvichetRL.php",
                                               type: "POST",      
                                               data: { "start": start },
                                               cache: false,                     
                                               success: function(response){                   
                                           
                                             TD (iddate);       
					     addrashetc (iddate); 

 }
                               });
                }
}
