Device name change

Question

Hi, 
 I know how to change the name of the device using 
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
err_code = sd_ble_gap_device_name_set(&sec_mode,(uint8_t const *) DEVICE_NAME, sizeof(DEVICE_NAME));
 
 No problem there. I know how to store it to pstorage. 
 But my question is where do I get the new name coming through . Basically where do I catch the characteristic change? 
 For my own services I have write handlers so I can capture it all there, but where do I put code in place to catch the change for the device name so I can store and restore? 
 Regards, 
 Chris

Bit of digging and found elsewhere but needed tweaking. 
 In my "main.c" I have this now 
 static void ble_gatt_params_on_ble_evt(ble_evt_t * p_ble_evt)
{
 ble_gatts_evt_write_t * p_evt_write = &p_ble_evt->evt.gatts_evt.params.write;
 
 if (p_evt_write->context.char_uuid.uuid == BLE_UUID_GAP_CHARACTERISTIC_DEVICE_NAME)
 {
 RMLOG("TODO: Name change attempt");
 
 // Device name is
 //p_evt_write->data;
 //p_evt_write->len;
 
 }
 
}
 
 And then in my main handler I do this 
 static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
 
 on_ble_evt(p_ble_evt);
 
 // Connection parameters
 ble_conn_params_on_ble_evt(p_ble_evt);
 
 // Device Name parameter
 ble_gatt_params_on_ble_evt(p_ble_evt);
 
 // Handle the sense service
 ble_sense_on_ble_evt(&m_sense, p_ble_evt);

 // Handle any Roam Core BLE services
 ble_rmcs_on_ble_evt(&m_rmcs, p_ble_evt);
 
 // Handle the Battery services
 ble_bas_on_ble_evt(&m_bas, p_ble_evt);

 // Anything for advertising to handle
 ble_advertising_on_ble_evt(p_ble_evt);

}
