Hi, currently the date being displayed in the grid is wrong

See more:

JQGrid

it displays the date – 1 (data in json march 2014 and in jqgrid it is displaying march 2011)
here is the snipped of the code

 { name: 'DateOfBirth', index: 'DateOfBirth', width: 100, align: 'center', formatter: 'date', srcformat: 'yyyy-mm-dd', newformat: 'm-d-y', edittype: 'text', editable: true, formoptions: { rowpos: 5, colpos: 1 },
                            editoptions:
{
    dataInit: function (el) {
        setTimeout(function () {
            $(el).datepicker();
        }, 200);
    }

can you please tell me how to fix this.
