jQuery Grid Plugin - jqGrid

so I`m in edit mode:

------------------------------
        onSelectRow: function(id){
          if(id){
            if(id!==lastsel2) jQuery('#editgrid').restoreRow(lastsel2);
            jQuery('#editgrid').editRow(id,true,picksec);
            lastsel2=id;
          }
        }
------------------------------

I`m trying to recreate the datepicker thing, but instead of datepicker, I want a ui dialog.

So I`ve created a function called picksec, that displays the dialog, but I don`t want it to display the dialog when I click wherever on the row for editing, I want it to display when I click on a exact column-name.

My colum name is ENUM, so how can I make this work somehow, to show my dialog

function picksec(id){ $('#izborsecnum').dialog('open'); }

this way it popups wherever I click on a row.
