How to update new set of data with the library?

[SumiGhosh]

For now, i just cloned the FragmentStatePagerAdapter and changed the code as below for destroyItem

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    Fragment fragment = (Fragment)object;

    if (mCurTransaction == null) {
        mCurTransaction = mFragmentManager.beginTransaction();
    }
    /*if (DEBUG) Log.v(TAG, "Removing item #" + position + ": f=" + object
            + " v=" + ((Fragment)object).getView());*/
    while (mSavedState.size() <= position) {
        mSavedState.add(null);
    }
    if(mFragments.size()>position){
        mSavedState.set(position, mFragmentManager.saveFragmentInstanceState(fragment));
        mFragments.set(position, null);

        mCurTransaction.remove(fragment);
    }
}

Currently it just working as it required.
