        {field:'productRevenue',title:'Revenue',footerFormatter:setTotalRevenue}
      ]

 function linkToOpenModel(value,row,index) {
  promotionId = row.promotionId ;
  asin = row.asin;
  return[
    '<a  href="#" onclick="OpenProductPromotionHistory('+ promotionId +','+asin+'); return 
 false;">',
    value,
    '</a>'
  ].join('')
 }

function OpenProductPromotionHistory(promotionId,asin) {
 var Myinfor =  'Promotion is ' +  promotionId +' and  asin is' + asin ;
