i tied this code to restart the tree

                                    b.DisableBehavior(false);//Stop Last BT
                                    b.EnableBehavior();
                                    b.SetVariableValue("Targets", targets);
                                    b.SendEvent<object>("Command", "Attack");

but when it restart it can not get the event ...

HasReceivedEvent will always receive the event, it just may not be reevaluated allowing you to capture that event. You should ensure the task is being reevaluated with a conditional abort.
