title: Angular ui grid disable sorting after cell edit
body: <p>For display tabular data , I am using angular ui-grid</p>
  
  <p>if a column is sorted and then if we edit the cell, the sorting gets kicked in and moves the row. I would like to disable sorting on cell edit, is there any way to do this?</p>

  <pre><code> &lt;div id="grid1" ui-grid="gridOptions" class="grid" ui-grid-edit &gt;
    &lt;/div&gt;
  
  var app = angular.module('app', ['ngAnimate', 'ngTouch', 'ui.grid','ui.grid.edit',
              'ui.grid.selection',
              'ui.grid.rowEdit', 'ui.grid.cellNav']);
  app.controller('MainCtrl', function($scope) {
    $scope.gridOptions = {
      enableSorting: true,
      columnDefs: [
        { field: 'A' },
        { field: 'B' },
        { field: 'C', enableSorting: false }
      ],
      onRegisterApi: function( gridApi ) {
        $scope.gridApi = gridApi;
      }
    };
  
    $scope.gridOptions.data = [{'A':'a1', 'B':'b1', 'C':'c1'}, {'A':'a3', 'B':'b3', 'C':'c3'}, {'A':'a2', 'B':'b2', 'C':'c2'}];
  
  });
