Android : listview with edittext repeats the values on scroll

This question has been asked frequently ..but nothing seems to work for me.

I have a listview with edittext .. when I scroll the listview value of edittext repeats.

Please suggest !!

code :

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

                View mView = view;             //trying to reuse a recycled view

                if (mView == null) {
                    //The view is not a recycled one: we have to inflate
                    mView = getActivity().getLayoutInflater().inflate(
                            getResource(), parent, false);
                    holder = new ViewHolder();


                    holder.row = (OEDataRow) moveLinesfinalData.get(position);

                    holder.eProductName = (TextView) mView.findViewById(R.id.textViewProductNameFinal);
                    holder.eProductName.setText(holder.row.getString("name").toString());

                    holder.innerLinearLayout = (LinearLayout) mView
                            .findViewById(R.id.innerLinearLayout);
                    holder.editTextProductId = (EditText) holder.innerLinearLayout
                            .findViewById(R.id.editTextProductId);
                    holder.eProductSerial = (EditText) holder.innerLinearLayout
                            .findViewById(R.id.editTextSerialFinal);

                    holder.BarCode = (Button) holder.innerLinearLayout.findViewById(R.id.buttonBarcode);
                    holder.editTextProductIdFocus = (EditText) holder.innerLinearLayout
                            .findViewById(R.id.editTextProductId);

                    mView.setTag(holder);
                } else {
                    // View recycled !
                    // no need to inflate
                    // no need to findViews by id
                    holder = (ViewHolder) mView.getTag();
                }

                if(holder.row != null) {
                    holder.editTextProductId.setText(holder.row.getInt("id").toString());

                }

                holder.eProductSerial.addTextChangedListener(new TextWatcher() {
                    @Override
                    public void onTextChanged(CharSequence s, int start, int before, int count) {
                    }
                    @Override
                    public void beforeTextChanged(CharSequence s, int start, int count,
                            int after) {
                    }
                    @Override
                    public void afterTextChanged(Editable s) {
                        String newSerial = s.toString();

                        String id = holder.editTextProductIdFocus.getText().toString();
                        productData.put(id,newSerial);

                    }
                });

                Log.d("list", "list productData "+productData);

                holder.BarCode.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        v.getId();
                    }
                });


                return mView;
            }
