Date note showing

[ledsled]

I am having issue getting date to actually show up at all. I get /Date(14300000000)/ and is continues in every sell.


   var obj = {
      width: "100%",
      height: 400,
        editable: false,
      //columnBorders: false,
      resizable: true,
      title: "Systems",
      showBottom: true,
      // maxColWidth: '50%',
      scrollModel: { autoFit: true },
      // flexHeight: true
      showTop: true,
      selectionModel: { type: 'cell' },
       pageModel: { type: "local", rPP: 20 },
        filterModel: { on: true, mode: "AND", header: true },
        numberCell: { show: false },
        showHeader: true,      
   };

   obj.columnTemplate = { minWidth: '10%', maxWidth: '80%' };
   obj.colModel = [
      { title: "Acronym", width: 10, dataIndx: "Acronym",
