Primefaces command button does not update datatable

I have primefaces command button multiple update problem. Command button is inside a form and datatable is not.

I have tried:

update=":datalist1,form1" 
update=":datalist1 form1" 
update="datalist1 form1"
update=":#{p:component('datalist1')},form1"

form1 updates every time but still dattable does not update

Version info:
primefaces: 5.3 
jsf: org.glassfish 2.3.0-m04
spring: 4.2.3
and I use cdi for controller beans

    public void createPersonel(){
        System.out.println("Personel adding..");
        personelService.create(personel);
        personel=new Personel();
        System.out.println("Personel added");
    }

}

I have researched about primefaces command button update but all advices did not worked for me. Thank you in advance

It seems to me that the newly created personel it never added to the list. So you must for example say

personels.add(personel);

or 

personels=personelService.findAll();

in createPersonel(), or set personels to null and do a lazy load in getPersonels().
