Storing v8::Persistent in map of structs

I'm trying to implements basic browser javascript setTimeout() using V8, but I have a trouble with storing Persistances. In callback I create v8::Handle function

v8::Handle<v8::Function> function = v8::Handle<v8::Function>::Cast(info[0]);

and cast it to CopyablePersistent

v8::Persistent<v8::Function, v8::CopyablePersistentTraits<v8::Function>> function_(getIsolate(), function);

For handling all callbacks, i create one loop which check every millisecond if we have a callbacks to execute. Callback's strored in std::map

typedef v8::Persistent<v8::Function, v8::CopyablePersistentTraits<v8::Function>> callbackCopyFunc;
enum TimeOutType { INTERVAL, ONCE };
struct TimeOutTask
{
    TimeOutType type;
    int timeout;
    int timePassed;
    callbackCopyFunc v8Function;
};
static std::map<uint64_t, TimeOutTask> timeOutTasks

The problem is that i can't access TimeOutTask.v8Function in this loop, i think because of v8::Persistent call Release() in destructor

V8_INLINE ~Persistent() {
    if (M::kResetInDestructor) this->Reset();
}
