Sorting not working using codebehind to set the data

[ChristianGalvez23]

I can't sorting using codebehind but working using [mfData]="array" attribute directly in tag component in view.

This is what I pretend to do (not working):

@ViewChild('mytable')
mytableComponent: DataTable;

private getMyArray(): void {
_[call to server]_
...
this.mytableComponent.data = array;
}
