Android checkbox.isChecked() does not work properly

I have a ListView in which a checkbox is displayed in each row.
Each and every time the checkbox is touched, I check wheteher it is checked or not.
But every time, the first item always return false. However, If if checked the 2nd item, the .ischecked() method of the checkbox of the first item alway return true.
Here is my code:

public class CustomSpecificCar extends ArrayAdapter<JSONObject>{
    ListSpecificCars caller;
    private JSONObject currentJson;
    private CheckBox cbSelectedCar;
    private int position;

    public CustomSpecificCar(Context ctxt, List<JSONObject> list, ListSpecificCars caller){
        super(ctxt, R.layout.custom_specific_car_row, list);
        this.caller = caller;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(getContext());
        View customView = inflater.inflate(R.layout.custom_specific_car_row, parent, false);
        this.position = position;

        // Set the reference of the layout
        currentJson                       = getItem(this.position);
        cbSelectedCar                     = (CheckBox)customView.findViewById(R.id.cbSelectedCar);
        TextView tvBrand                  = (TextView)customView.findViewById(R.id.tvBrand);
        TextView tvModel                  = (TextView)customView.findViewById(R.id.tvModel);
        TextView tvOwnerEditable          = (TextView)customView.findViewById(R.id.tvOwnerEditable);
        TextView tvPriceEditable          = (TextView)customView.findViewById(R.id.tvEstimatedPriceEditable);


        try {
            tvBrand.setText(currentJson.getString("brand"));
            tvModel.setText(currentJson.getString("model"));
            tvOwnerEditable.setText(currentJson.getString("owner"));
        } catch (JSONException e) {
            Log.e(e.getClass().getName(), "JSONException", e);
        }

        cbSelectedCar.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                    if (cbSelectedCar.isChecked()){
                        caller.updateClickedUsername(currentJson, true); // Add to the List
                        Log.d("Added click ", "ok");
                    }

                    else if (!cbSelectedCar.isChecked()) {
                        caller.updateClickedUsername(currentJson, false); // Delete from the List
                        Log.d("Deleted click ", "nok");
                    }
        }});

        return customView;
    }

}

What should I do to solve this issue? Many thanks in advance!

You should use setOnCheckedChangeListener.

Sample:

  checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
            boolean isChecked) {

        }
      });

In your code:

    cbSelectedCar.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
            boolean isChecked) {
              if (isChecked){
                    caller.updateClickedUsername(currentJson, true); // Add to the List
                    Log.d("Added click ", "ok");
                }

                else if (!isChecked) {
                    caller.updateClickedUsername(currentJson, false); // Delete from the List
                    Log.d("Deleted click ", "nok");
                }

        }
      });
