Hi,
Your sample works as expected...
I cant seem to get it to work with a async data fetching -  http call or any other way.
with a synchronous data source, it seems to work.
 
You can even just add a settTimeout of a second or two in the render event before calling the fetchData() method in your sample.

rendered: (ev, ui) => {
   setTimeout(()=> {
      this.fetchData(ui.owner);
   },1000);
}

thanks

Hello Amos,

When you set a dataSource it calls the dataBind method automatically.

I am attaching a working sample.

Please let me know if I could be of further assistance.

Hi,
Thanks for the response.

I uploaded files to show my case.
the files are taken from the Angular2 sample page on github.

these two file are the igComboTemplate.html file - where I just gave the control an id, and the second file the the app.ts, where I changed the code so the data will be fetched with a 3 seconds delay, to mock the data fetching from the server.

so i order to get the sample going, you will need to get the "igniteui-angular2-master" from https://github.com/IgniteUI/igniteui-angular2
and replace these two files in the igCombo directory.

thanks in advance
