Now this changes the model but after round restart

How can can it be so that model is changed instandly without of needing restartround
Code:
#include <amxmodx>
#include <cstrike>
enum
{
TEAM_UNASSIGNED,
TEAM_T,
TEAM_CT,
TEAM_SPECTATOR
};
public plugin_precache() {
precache_model("models/player/smith/smith.mdl")
precache_model("models/player/smith/smith.mdl")
}
public plugin_init() {
register_plugin("Vip Model", "1.0", "Author");
register_event("ResetHUD", "ResetHUD", "be");
}
public ResetHUD(Client) {
if (!is_user_alive(Client))
return;
new CsTeams:Team = cs_get_user_team(Client);
switch (Team)
{
case TEAM_T:
{
if (get_user_flags(Client) & ADMIN_BAN) cs_set_user_model(Client, "smith");
else cs_reset_user_model(Client);
}
case TEAM_CT:
{
if (get_user_flags(Client) & ADMIN_BAN) cs_set_user_model(Client, "smith");
else cs_reset_user_model(Client);
}
}
}
