Viewpager not updating correctly - android-fragments

Question

I am creating an application which has an activity which contains viewpager and this viewpager acts as a container for six fragments. The activity also has a spinner which contains 8 items. The thing which I am trying to achieve is that when I select an item from a spinner then fragments inside viewpager should be destroyed and six new fragments should be populated.
I am using a FragmentStatePagerAdapter to achieve this.
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager manager, ArrayList<Fragment> fmList) {
super(manager);
pagerFragmentList = fmList;
}
#Override
public Fragment getItem(int position) {
return pagerFragmentList.get(position);
}
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
#Override
public int getCount() {
return pagerFragmentList.size();
}
}
This is how I load new data.
pagerFragmentList.clear();
pagerFragmentList = newFragmentList;
mPagerAdapter.notifyDataSetChanged();
mPager.setCurrentItem(0);
As I told that I have six fragments inside viewpager and 8 items inside spinner so that makes total of 48 fragment classes but thing is that I am only using six xml layout files for my view and I inflate these views inside all my fragments.
First time when fragments are loaded everything works fine but when I select an item from a spinner then the fragment shows me pre-entered values which I entered when first item of spinner was selected.
This is the snapshot of my app

Im not sure but you can try this way
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager manager, ArrayList<Fragment> fmList) {
super(manager);
pagerFragmentList = fmList;
}
#Override
public Fragment getItem(int position) {
return pagerFragmentList.get(position);
}
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
#Override
public int getCount() {
return pagerFragmentList.size();
}
public void mDatasetChanged(ArrayList<Fragment> mFmList){
pagerFragmentList = mFmList;
this.notifyDataSetChanged();
}
}
And then in your activity
pagerFragmentList.clear();
pagerFragmentList = newFragmentList;
mPagerAdapter.mDatasetChanged(pagerFragmentList);
mPager.setCurrentItem(0);
