jQuery Grid Plugin - jqGrid

hi,

 jQuery("#list2").jqGrid({
     datatype: 'local',
    height:400,
    colNames:['check','test'],
    colModel :[
      {name:'check'', index:'check'', width:55, sorttype:'int', hidden:true,align:'center',classes:"JqGrid"}, 
       {name:'test', index:'test',width:75,align:'center',classes:"JqGrid"}
       ],
   pager: '#pager2',
 scroll: 0,
    rowNum:0,
    viewrecords: true,
    caption: '',
    gridComplete: function(){
    var ids = jQuery("#list2").jqGrid('getDataIDs');
  
       for(var i=0;i < ids.length;i++)
       {
       var cl = ids[i];
       be = "<input style='width:75px;' id='showreport" + i + "' type='button' value='look' onclick="javascript:return doBack();"  />";
       jQuery("#list2").jqGrid('setRowData',ids[i],{test:be});
    
       }
     

    }

hi, this is just like the demo, and it works fine. the test column will show the buttons. But I need to get the button's id, in order to do somthing else.

I tried:

jQuery("#showreport1").attr("value","123");

but no luck, it seems can't affact the button's value at all. I think maybe the jqgrid change the input button's id by itself?

Please tell me how it construct it.

yours,

Ivan
