HUD Elems - Where did I go wrong?

[CamxxCore]

If anyone can help me with this, I will appreciate it very much. I've been trying to get HUD elements working on the latest patch but haven't had much luck. Everything looks right to me, but I still can't get anything to actually show up in-game. If there is something clearly wrong with how I am doing this, please tell me. I'm using the exact same method that has been used on consoles to achieve the same result. I am new and still learning, so please go easy!

int GetMaterialIndex(const char* materialName)
{
	return ((int(__cdecl*)(const char*))0x54D620)(materialName);
}

int G_LocalizedStringIndex(const char* text)
{
	return ((int(__cdecl*)(const char*))0x54D490)(text);
}

game_hudelem_s* HudElemAlloc(int client, int teamNum)
{
	return ((game_hudelem_s*(__cdecl*)(int, int))0x5293E0)(client, teamNum);
}

void func()
{
	// spawn a hud element
	game_hudelem_s* elem = HudElemAlloc(0, 0);
	elem->clientNum = 0;
	elem->elem.type = 1;
	elem->elem.text = G_LocalizedStringIndex("Hello, world.");
	elem->elem.font = 1;
	elem->elem.fontScale = 10;
	elem->elem.x = 250;
	elem->elem.y = 100;
	elem->elem.alignOrg = 1;
	elem->elem.alignScreen = 6;
	elem->elem.color.r = 255;
	elem->elem.color.g = 255;
	elem->elem.color.b = 255;
	elem->elem.color.a = 255;
	elem->elem.glowColor.r = 255;
	elem->elem.glowColor.g = 255;
	elem->elem.glowColor.b = 255;
	elem->elem.glowColor.a = 255;

	// nothing! :(
