Working Link Here

"render": function(data, type, full, meta ) {
    if (full.info != 'N/A') {
        return "<button href='" + row.index() + "' class='btn btn-info'>View</button>"
    } else {
        return ""
    }
}

Render is documented here: https://datatables.net/reference/option/columns.render

You aren't using the same name of arguments documented there, but in the examples, you would use full to access all of the available columns and data is the current column. I'm not sure where you got field from. So data from info would be accessed at full.info.

An example being:

"render": function ( data, type, full, meta ) {
  return '<a href="'+data+'">' + full.info + '</a>';
}
