How to implement onload js event for TUniImage component?

[rgreat]

Tried this:

Draw: TUniImage;

UniSession.AddJS( '$("#"+MainForm.Draw.nm+"_id").find("img:first").load(function() { alert("!"); } );' );

But it's fire only once on page load.

 

After that at runtime i do:

Draw.Picture.Bitmap.Assign(SomeBmp);

But event does not fire.
 

 

Do i need to free and recreate Draw at runtime?

Any ideas?
