Im trying to create a sample application following the example in https://developer.tizen.org/ko/development/guides/native-application/user-interface/efl/ui-components/wearable-ui-components/circle-progressbar for wearable-4.0 but the text in the center of progress bar does not show at all as illustrated in the sample picture.

Im using the following code as instructed.

static void create_base_gui(appdata_s *ad) {
    /* Window */
    /* Create and initialize elm_win,
       which is mandatory to manipulate a window
    */
    ad->win = elm_win_util_standard_add(PACKAGE, PACKAGE);
    elm_win_autodel_set(ad->win, EINA_TRUE);

    if (elm_win_wm_rotation_supported_get(ad->win)) {
        int rots[4] = {0, 90, 180, 270};
        elm_win_wm_rotation_available_rotations_set(ad->win, (const int *)(&rots), 4);
    }

    evas_object_smart_callback_add(ad->win, "delete,request", win_delete_request_cb, NULL);
    eext_object_event_callback_add(ad->win, EEXT_CALLBACK_BACK, win_back_cb, ad);

    /* Conformant */
    /* Create and initialize elm_conformant,
       which is mandatory for the base UI to have a proper size
       when an indicator or virtual keypad is visible
    */
    ad->conform = elm_conformant_add(ad->win);
    elm_win_indicator_mode_set(ad->win, ELM_WIN_INDICATOR_HIDE);
    evas_object_size_hint_weight_set(ad->conform, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
    elm_win_resize_object_add(ad->win, ad->conform);
    evas_object_show(ad->conform);

    /* Naviframe */
    ad->naviFrame = elm_naviframe_add(ad->conform);
    evas_object_show(ad->naviFrame);
    elm_naviframe_prev_btn_auto_pushed_set(ad->naviFrame, EINA_TRUE);
    elm_object_content_set(ad->conform, ad->naviFrame);

    /* Starting right after the basic EFL UI layout code */
	/* (win - conformant - naviframe) */

	/* Set a circle surface */
	ad->circleSurface = eext_circle_surface_conformant_add(ad->conform);

	/* Add a layout and push the layout into the naviframe */
	/* EDJ_PATH is folder path, it contains the progressbar_circle.edj file */
	ad->progressBarLayout = elm_layout_add(ad->naviFrame);
	elm_layout_file_set(ad->progressBarLayout, "res/progressbar_circle.edj", "eext_progressbar_layout");
	evas_object_show(ad->progressBarLayout);
	elm_naviframe_item_push(ad->naviFrame, NULL, NULL, NULL, ad->progressBarLayout, NULL);

	/* Add a progressbar and set a circle surface to render the progressbar */
	ad->progressBar = eext_circle_object_progressbar_add(ad->progressBarLayout, ad->circleSurface);
	/*Set a minimum and maximum values */
	eext_circle_object_value_min_max_set(ad->progressBar, 0.0, 100.0);
	/* Set a progressbar value */
	eext_circle_object_value_set(ad->progressBar, 0);
	/* Set a part content */
	elm_object_part_content_set(ad->progressBarLayout, "elm.swallow.content", ad->progressBar);
	evas_object_show(ad->progressBar);

	/* Set a text */
	elm_object_part_text_set(ad->progressBarLayout, "elm.text.progressbar", "10");

	evas_object_show(ad->win);

}

               rel2.relative: 0.5 0.5;
               text {
                  font: "Tizen:style=Regular";
                  size: 50;
                  min: 1 1;
                  ellipsis: -1;
               }
               color: 255 255 255 255;
            }
         }
      }
   }
}

Can you see any issue with my implementation? I tried both in emu. and Galaxy watch.
