Should I delete the pointer manually in v8 :: External?

Question

Local<ObjectTemplate> tpl = ObjectTemplate::New(isolate);
tpl->SetInternalFieldCount(1);
Local<Object> ret = tpl->NewInstance();
TestExternal* ex = new TestExternal();
ret->SetInternalField(0, External::New(isolate, ex));

Is it possible to delete the pointer exmanually if it is retno longer in use?

Where does the source code for the evidence show that I should or should not?
