redux action fails

test.js

//calling module
import { setTab } from "../../../shared/store/actions/navAction";

<Tab
  label={translate.tabAll}
  selected={tab === 1}
  onPress={() => {
    setTab(1); //no console response when selected
  }}
/>

// action types
export const SET_TAB = "SET_TAB";

//navAction
import { SET_TAB } from "./actionTypes";

export const setTab = (tab) => {
  console.log("setTab action"); // log output
  return async (dispatch) => {
    console.log("setTab return"); // no log output
    dispatch({
      type: SET_TAB,
      payload: tab,
    });
  };
};

//navReducer
import { SET_TAB } from "../../store/actions/actionTypes";

const initialState = {
  selectedTab: 1,
};

export default (state = initialState, action) => {
  switch (action.type) {
    case SET_TAB:
      return {
        ...state,
        selectedTab: action.payload,
      };
      // blah blah... more cases

    default:
      return state;
  }
};
