I agree with biegleux... But my suggestion is

public class CategoryFragment extends Fragment{

   private static CategoryFragment categoryFrag;

    private CategoryFragment(){}

    public static CategoryFragment getInstance(){
        if(null == categoryFrag){
            categoryFrag = new CategoryFragment();
        }

        return categoryFrag;
    }

    public void  getData(){
       /*** Screen Refresh code****/
    }
} 

I your active when he selects option

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
                case R.id.menu_refresh:
                    CategoryFragment fragment = CategoryFragment.getInstance();
                     fragment.getData();

                    return true;
                default:
                    return super.onOptionsItemSelected(item);
    }
