IllegalStateException on adding parallax header

Hi,

I was trying to implement parallax scrolling using this awesome library. But I ran into some problems. Am not sure I'm doing this right(first time android programmer). I'm getting this on adding parallaxheader.

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() >on the child's parent first.

I'll just give you a brief idea of what I did. I have a chart which is the header. So I extended your ParallaxRecyclerAdapter with a custom constructor, overrode some methods, and named it StatsAdapter

 public StatsAdapter(LineChartData mChartData, final List<StatsItem> mListData) {
        super(mListData);
      this.mListData = mListData;
        this.mChartData = mChartData;
        implementRecyclerAdapterMethods(this);
    }

And overrode setParallaxHeader like this

 public void setParallaxHeader(View header, RecyclerView view) {
        LineChartView chart = (LineChartView) header.findViewById(R.id.chart);
        chart.setLineChartData(mChartData);
        formatChart(chart);
        super.setParallaxHeader(header, view);
    }

And in the Fragment from which I'm loading the recyclerview, I did this

 mRecyclerView = (RecyclerView) rootView.findViewById(R.id.stats_recycler_view);
        mRecyclerView.setHasFixedSize(true);
        mLayoutManager = new LinearLayoutManager(getActivity());
        mRecyclerView.setLayoutManager(mLayoutManager);
        mStatsAdapter = new StatsAdapter(mChartData, mListData);
        mHeaderView = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_chart_detail,mRecyclerView,false);
        mStatsAdapter.setParallaxHeader(mHeaderView, mRecyclerView);
        mRecyclerView.setAdapter(mStatsAdapter);

Any idea why I'm getting this error?
