It will not work with the current primeui (at the time of this answer it is 1.1). Have a look at the sort function:
sort: function(field, order) {
if(this.options.selectionMode) {
this.selection = [];
}
if(this.options.lazy) {
this.options.datasource.call(this, this._onLazyLoad, this._createStateMeta());
}
else {
this.data.sort(function(data1, data2) {
var value1 = data1[field],
value2 = data2[field],
result = (value1 < value2) ? -1 : (value1 > value2) ? 1 : 0;
return (order * result);
});
if(this.options.selectionMode) {
this.selection = [];
}
if(this.paginator) {
this.paginator.puipaginator('option', 'page', 0);
}
this._renderData();
}
},
As you can see it uses the Array.prototype.sort() function and accesses the field-to
var value1 = data1[field],
value2 = data2[field],
Maybe you can override this particular function and use your own sort method instead.

since prime-ui uses jquery-ui, is there any way, we can use the sort functionality of the jquery datatable ? If yes, please give an example – Pii Apr 30 '15 at 06:33

What is 'the jquery datatable'? I did not find any datatable at https://jqueryui.com/ – Manuel Apr 30 '15 at 07:11

Try to override the prime-ui's sort function. Then you can order like you want to. – Manuel May 12 '15 at 07:50
