C++ Tfs 1.2 New attribute key

[Hidroponica]

Hello everyone, Im editing my sources trying to add a new attribute to the game using example like this post Feature - [TFS 1.2] Reflection attribute

but the effect of the attribute only works when i relog my character

here are some of my editions
could someone tell me what i can do to proceed

enums.h

    ITEM_ATTRIBUTE_EXTRAMELEE = 1 << 27,

player.h

        int32_t getExtraMelee() const {
            if (hasAttribute(ITEM_ATTRIBUTE_EXTRAMELEE)) {
                return getIntAttr(ITEM_ATTRIBUTE_EXTRAMELEE);
            }
            return items[id].extraMelee;
        }

player.cpp

case ATTR_EXTRAMELEE: {
            int32_t extraMelee;
            if (!propStream.read<int32_t>(extraMelee)) {
                std::cout << "ATTR_EXTRAMELEE: " << "READ ERRORi: " << ATTR_READ_ERROR << std::endl;
                return ATTR_READ_ERROR;  
            }
            std::cout << "setIntAttr: " << extraMelee << std::endl;
            setIntAttr(ITEM_ATTRIBUTE_EXTRAMELEE, extraMelee);
            break;
        }


    if (hasAttribute(ITEM_ATTRIBUTE_EXTRAMELEE)) {
        std::cout << "hasAttribute(ITEM_ATTRIBUTE_EXTRAMELEE)" << std::endl;
        propWriteStream.write<uint8_t>(ATTR_EXTRAMELEE);
        propWriteStream.write<int32_t>(getIntAttr(ITEM_ATTRIBUTE_EXTRAMELEE));
    }

player.h

changed this place :
uint16_t getSkillLevel(uint8_t skill) const {
            int v = (int) getVocationId();
            if (v != 4 && v != 5 && v != 7 && v != 8 && v != 11 && v != 12) {
                return std::max<int32_t>(0, skills[skill].level + varSkills[skill]);
            }
            return std::max<int32_t>(0, skills[skill].level + varSkills[skill] + getExtraMelee());
        }

player.cpp

int32_t Player::getExtraMelee() const
{
    int32_t melee = 0;
    static const slots_t all[] = {CONST_SLOT_HEAD, CONST_SLOT_NECKLACE, CONST_SLOT_ARMOR, CONST_SLOT_LEGS, CONST_SLOT_FEET, CONST_SLOT_RING, CONST_SLOT_RIGHT, CONST_SLOT_LEFT};

    for (slots_t slot : all) {
        Item* inventoryItem = inventory[slot];
        if (inventoryItem)
            melee += inventoryItem->getExtraMelee();
    }

    return melee;
}
