Android : Custom Cursor Adapter not printing Values and EditText

I have been working with my custom cursor adapter and have run into a problem, the layout of the row is | textView| Button | editText | Button |. When a button is clicked a number in the edit text will either be incremented or decremented. At the moment it all works with one row, but when I add a second row the counter carries to the new row. How do I make it so that when I add a new row it will have its own separate counter variable? I am also having trouble with the text view, instead of printing the value from the database it is just prints out nothing. How do I fix these problems?

This is the custom Cursor adapter class I am using

package com.example.rory.dbtest;
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CursorAdapter;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.pinchtapzoom.R;


public class CustomCursorAdapter extends CursorAdapter{

public int counter = 0;

public CustomCursorAdapter(Context context, Cursor c) {

    super(context, c);
    this.context = context;
}
Context context;


@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    // when the view will be created for first time,
    // we need to tell the adapters, how each item will look
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View retView = inflater.inflate(R.layout.row, parent, false);

    return retView;
}

@Override
public void bindView(View view, Context context, Cursor cursor) {
    // here we are setting our data
    // that means, take the data from the cursor and put it in views

    TextView textViewPersonName = (TextView) view.findViewById(R.id.item1);
    textViewPersonName.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(0))));

}

public View getView(final int position, View convertView, ViewGroup parent)
{
    if (convertView == null)
    {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        convertView = (RelativeLayout)inflater.inflate(R.layout.row, null);
    }

    final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
    Button plusButton = (Button) convertView.findViewById(R.id.plusButton);
    plusButton.setOnClickListener(new View.OnClickListener()
    {
       public void onClick(View v)
       {
           counter++;
           edit1.setText(Integer.toString(counter));

       }
    });

    //final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
    Button minusButton = (Button) convertView.findViewById(R.id.minusButton);
    minusButton.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View v)
        {
            counter = counter--;
            edit1.setText(Integer.toString(counter));
        }
    });
    return convertView;
}
}

And this is the XML file I am using

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<TextView android:id="@+id/item1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="30sp"
    android:paddingBottom="5dp"/>

<Button
    android:id="@+id/plusButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/plusButton"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true" />

<EditText
    android:id="@+id/runningTotal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_toLeftOf="@+id/minusButton"
    android:layout_toStartOf="@+id/minusButton"
    android:layout_marginRight="30dp" />

<Button
    android:id="@+id/minusButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/minusButton"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />



</RelativeLayout>
