Holder returning wrong values

Question

In my getView method when I am trying click an imagebutton of a view,Imagebutton of its adjacent view is being clicked and same for the other UI's,which means it is returning wrong view each time.I am not able to figure out where the problem is.

Adapter Class

public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ImageView iv;
    //View v = convertView;
    String content = null;
    LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if(convertView==null) {
        convertView=inflater.inflate(R.layout.row_item2,parent,false);
        holder = new ViewHolder();  
        pos=position;



        holder.read_more=(TextView)convertView.findViewById(R.id.readMore);
        holder.share=(TextView)convertView.findViewById(R.id.share);
        holder.heading = (TextView)convertView.findViewById(R.id.heading);
        holder.date = (TextView)convertView.findViewById(R.id.date);
        holder.message = (TextView)convertView.findViewById(R.id.message);
        holder.gridview=(GridView)convertView.findViewById(R.id.grid_view);
        holder.comment_executed=(ImageView)convertView.findViewById(R.id.comments);
        holder.image=(ImageView)convertView.findViewById(R.id.img);
        holder.like_img=(ImageButton)convertView.findViewById(R.id.like);
        convertView.setTag(holder);

    }else {
        holder=(ViewHolder)convertView.getTag();
    }
    holder.read_more.setVisibility(View.GONE);
    holder.image.setVisibility(View.GONE);
    holder.gridview.setVisibility(View.GONE);
    holder.heading.setText(Html.fromHtml(modelList.get(position).getTitle()));
    //String setDate=parseDate(modelList.get(position).getDate());

    holder.like_img.setOnClickListener(new View.OnClickListener() {

You need to notify after performing any changes.

holder.like_img.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(context,holder.heading.getText()+" "+modelList.get(position).getTitle(), Toast.LENGTH_SHORT).show();
            holder.like_img.setImageResource(R.drawable.up_arrow_hover);
            notifyDataSetChanged();//notify after any changes
        }
    });
