Custom Adapter ListView, setOnCheckedChangeListener not working

Question

I have read 15+ questions on this topic and none of the solutions have worked for me yet.

I have created a custom Adapter to populate a ListView. Each ListView row contains a single checkbox, and I am trying to capture the checked change event within my custom adapter using setOnCheckedChangeListener.

When I run the app, I get a null pointer exception on the setOnCheckedChangeListener line.

Here is my custom adapter class:

package com.android.toneturtle;

import java.util.ArrayList;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;

public class ListAdapterPlaylist extends BaseAdapter{
    private ArrayList<Playlist> playlists;
    private Context context;
    LayoutInflater inflater;

    public ListAdapterPlaylist(Context context, ArrayList<Playlist> playlists){
        this.context = context;
        this.playlists = playlists;
        inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public int getCount() {
        // return the number of records in cursor
        return playlists.size();
    }

    @Override
    public Object getItem(int position) {
        return playlists.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View view, ViewGroup parent) {

        if(view==null) {
            view = inflater.inflate(R.layout.playlist_items, parent, false);
        }

        TextView name = (TextView)view.findViewById(R.id.text_view);
        name.setText(playlists.get(position).getName());

        CheckBox checkbox = (CheckBox)view.findViewById(R.id.checkbox);
        checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                Log.d("test","i work!");
            }   
        }); 
        return view;
    }
}

If anyone could give me a hand with this problem I would be very grateful.

edit: Here is the error logcat

Thankyou Richa for your help.

I had an incorrect id name in the row.xml file.
