Nested fragment with viewpager where viewpager not loading the fragments

Question

I have a activity in which i am loading a fragment

Home fragmentA = new Home();
        android.support.v4.app.FragmentTransaction fragmentTransactionA = getSupportFragmentManager().beginTransaction();
        fragmentTransactionA.replace(R.id.mainFrame, fragmentA);
        fragmentTransactionA.commitAllowingStateLoss();

in my home fragment i have a slidingtablayout and viewpager

and my java code of my home fragment is this

public class Home extends Fragment {

    View infHome;
    SlidingTabLayout slidingTabLayout;
    ViewPager viewPager;
    private FragmentPageAdapterHome Pa;
    CharSequence Titles[] = {"Requirements", "Notification"};
    int Numboftabs = 2;

    public Home() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        infHome = inflater.inflate(R.layout.fragment_home2, container, false);

        return infHome;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        slidingTabLayout = (SlidingTabLayout) infHome.findViewById(R.id.sliding_tabs);
        viewPager = (android.support.v4.view.ViewPager) infHome.findViewById(R.id.viewpager);

        // adapter = new ViewPagerAdapter(getResources(), getChildFragmentManager());
        //  FragmentManager fragmentManager = getChildFragmentManager();
        Pa = new FragmentPageAdapterHome(getChildFragmentManager(), Titles, Numboftabs, getActivity().getApplicationContext());
        viewPager.setAdapter(Pa);
        slidingTabLayout.setSelectedIndicatorColors(Color.parseColor("#0bbea5"));
        slidingTabLayout.setDistributeEvenly(true);
        slidingTabLayout.setViewPager(viewPager);
    }

}

And my FragmentPageAdapterHome is this

import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.util.Log;
import android.view.ViewGroup;

import java.util.HashMap;
import java.util.Map;

import mobile.data.woises.fragment.Notification;
import mobile.data.woises.fragment.Requirements;

/*import com.example.uday.innohabit.fragments.FragA;
import com.example.uday.innohabit.fragments.FragB;
import com.example.uday.innohabit.fragments.FragC;*/

        switch (arg0) {
            case 0:
                Requirements requirements = new Requirements();
                return requirements;
            case 1:
                Notification notification = new Notification();
                return notification;
            default:
                break;
        }
        return null;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return Titles[position];
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return NumofTabs;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Object obj = super.instantiateItem(container, position);
        if (obj instanceof Fragment) {
            // record the fragment tag here.
            Fragment f = (Fragment) obj;
            String tag = f.getTag();
            mFragmentTags.put(position, tag);
        }
        return obj;
    }

    public Fragment getFragment(int position) {
        String tag = mFragmentTags.get(position);
        if (tag == null)
            return null;
        return mFragmentManager.findFragmentByTag(tag);
    }
}

all the Log in the Requirement and the notification fragment is being displayed in Logcat that means the function is being called but the fragment is not being displayed please help me where i am making the mistake . I was using the getsupportfragmentmanager() but someone on stack overflow posted that i should use the getChildFragmentManager() when it is nested fragment . what should i do .please help me i am unable to figure out what is problem.
