Soft-Keyboard hidden when coneccted hid keyboard

Hi, I am developing hid device using nrf5 SDK. Iphone virtual keyboard does not shown when my hid device connected. What should I do? Which command Ihave to send Iphone over HID? or How should I re-design my report map?

Here is my hids_init function.

static void hids_init(void)
{
    ret_code_t                    err_code;
    ble_hids_init_t               hids_init_obj;
    ble_hids_inp_rep_init_t     * p_input_report;
    ble_hids_outp_rep_init_t    * p_output_report;
    ble_hids_feature_rep_init_t * p_feature_report;
    uint8_t                       hid_info_flags;

    static ble_hids_inp_rep_init_t     input_report_array[2];
    static ble_hids_outp_rep_init_t    output_report_array[2];
    static ble_hids_feature_rep_init_t feature_report_array[1];
    static uint8_t                     report_map_data[] =
