How to sort by default with a custom function

[kilofafeure]

Hi, I'm trying to sort the first time that I load the table with a custom function but I can't achieve it. The custom function works fine, but when I load the table all the columns are disordered. If I put a column that haven't a custom function the first time is well ordered.

• I've tried to use my custom function into the sortBy param:
  public sortBy = this.sortByTitle ;
• I' ve tried to put the Title column name into the the sortBy param:
  public sortBy = "Title";
• I've tried to call my custom function after receive all the data list from the server but doesn't works too.

** My Custom function
private sortByTitle = (a: OperationEnterpriseLawyer_Grouped) => { var strWithAccent = a.Title; var strWithoutAccent: string = _.deburr(strWithAccent).toLowerCase(); return strWithoutAccent; }
