How to change the default sort mechanism of grid column

[samir_ware]

Helllo All
I am willing to have custom sorting mechanism for column sorting in grid. Is there any hook EXT has provided for such custom sorting ?
Thanks
Samir

It looks like sortType can only sort a list on the model level. Is there a way to define a sort on the grid column?

I know this is a bit late, but I came up with a way of doing it for columns in Ext JS 5, seeing as how doSort was taken out. I decided to listen to the sortchange event, and from there, use the Ext.data.Store.setSorters method. Excuse the complex sorterFn, but here's the relevant code (and Fiddle):

// grid class
initComponent: function() {
  ...
  this.on('sortchange', this.onSortChange, this);
},

onSortChange: function(container, column, direction, eOpts) {
  // check for dayColumnIndex
  if (column && column.dayColumnIndex !== undefined) {
    this.sortColumnByIndex(column.dayColumnIndex, direction);
  }
},

sortColumnByIndex: function(columnIndex, direction) {
  var store = this.getStore();
  if (store) {
    var sorterFn = function(rec1, rec2) {
      var sortValue = false;
      if (rec1 && rec2) {
        var day1;
        var daysStore1 = rec1.getDaysStore();
        if (daysStore1) {
          day1 = daysStore1.getAt(columnIndex);
        }
        var day2;
        var daysStore2 = rec2.getDaysStore();
        if (daysStore2) {
          day2 = daysStore2.getAt(columnIndex);
        }
        if (day1 && day2) {
          sortValue = day1.get('value') > day2.get('value');
        }
      }
      return sortValue;
    };
    if (direction !== 'ASC') {
      sorterFn = function(rec1, rec2) {
        var sortValue = false;
        if (rec1 && rec2) {
          var day1;
          var daysStore1 = rec1.getDaysStore();
          if (daysStore1) {
            day1 = daysStore1.getAt(columnIndex);
          }
          var day2;
          var daysStore2 = rec2.getDaysStore();
          if (daysStore2) {
            day2 = daysStore2.getAt(columnIndex);
          }
          if (day1 && day2) {
            sortValue = day1.get('value') < day2.get('value');
          }
        }
        return sortValue;
      };
    }
    // this is the key to it all right here
    store.setSorters([{
      sorterFn: sorterFn
    }]);
  }
}
