wait setState to finish, using optional callback parameters

Comment

// From this
this.setState(
  {
    something: new
  },
);
  this.execute()  //this function execute before setState finished

// To This
this.setState(
  {
    something:new
  },
  this.execute()  //this function waits. setState() have optional callback parameter
);

//the callback must be a function, "console.log(something)" should be "()=>{console.log(something)"
