While working with Fragment, you have to inflate view.

So when you want to use any widget you have to use view object with findViewById().

Simply Do like this...

public class HomeFragment extends Fragment {

    public HomeFragment(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_home, container, false);

            btnCheckFalAction = (Button) rootView.findViewById(R.id.btnCheckFal); // you have to use rootview object..
            btnCheckFalAction.setOnClickListener(new OnClickListener() {           

                  @Override
                  public void onClick(View v) 
                  {
                      Toast.makeText(getActivity(), "Hello World", Toast.LENGTH_LONG).show();
                  }    
                });

        return rootView;
    }
}

OR try other way..

public class HomeFragment extends Fragment implements OnClickListener{

    public HomeFragment(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_home, container, false);

            btnCheckFalAction = (Button) rootView.findViewById(R.id.btnCheckFal); // you have to use rootview object..
            btnCheckFalAction.setOnClickListener(this);

        return rootView;
    }
    @Override
    public void onClick(View v) {
     // TODO Auto-generated method stub
     switch(v.getId()){

     case R.id.btnCheckFal :
         //your code...
     break;

    default:
        break;

     }

    }
}
