How to move cursor from Second Column to First Column in a new row in jqgrid

I am new to jqgrid. I have the following code to insert a new row when a tab key is pressed. It works for the most part of it. But when a new row is inserted, the focus is given to the second Column in that row instead of First column.

How do I solve this problem??

HTML:

 <table  id="list11"></table>
 <!--<div id="paddtree"></div>-->
 <label>press tab to add new row</label>
<script>
    var selIRow = 1;
        var lastsel2
        jQuery("#list11").jqGrid({
    // url:'d/${jobId}.htm',
            datatype: "json",
            colNames: ['First Name', 'Email ID', 'Phone Number'],
            colModel: [
                // {name:'id',index:'id', width:75, search:true, stype:'text' , search:true, sortable:true},
                {name: 'firstName', width: 180, search: true, stype: 'text', sortable: true, editable: true, },
                {name: 'email', index: 'email', width: 250, editable: true},
                {name: 'phoneNumber', index: 'phoneNumber', width: 100, align: "right", editable: true,
                    editoptions: {
                        dataInit: function(elem) {
                            $(elem).focus(function() {
                                this.select();
                            })
                        },
                        dataEvents: [
                            {
                                type: 'keydown',
                                fn: function(e) {
                                    var key = e.charCode || e.keyCode;
                                    if (key == 9 || key == 15)//tab
                                    {
                                        var grid = $('#list11');
                                        //Save editing for current row
                                        grid.jqGrid('saveRow', selIRow, false, 'clientArray');
                                        //If at bottom of grid, create new row
