cheers for that - I have modified our html accordingly and the event now fires - see http://webix.com/snippet/296a8249. Unfortunately the combo is not rendering ok any more due to now having a webix-ui attribute.
In http://docs.webix.com/desktop__angular.html it says ‘Note that any HTML outside “webix-ui” block is parsed as standard markup while a div with webix-ui attribute constructs Webix app.’ - what are the rendering implications of this?
When you are using webix-ui directive, lib starts a new interface block at this point, which looks as static HTML for the parent block. So the most problematic side-effect of nested webix-ui usage is a broken sizing. The parent component can’t correctly detect a size of child webix-ui block and visual rendering degrades.
