Automate Ember.js application using Selenium when object proerties are changed at run-time

I am trying to automate an Ember.js application using Selenium+TestNg.

The drop-down in the application has only one object property id. However every time i refresh the Page id gets change and there is not pattern. Eg: First time i open a page id=ember1398 and when i refresh the page same object id changes to ember1097.

I would be greatful if some one can guide me in overcoming this challenge. I am open to change tool/framework if necessary.
