I started using the recently released Grouping functionality for the DropDownList widget. While using it, I noticed a possible bug while using it with MVVM.
See the following jsfiddle: http://jsfiddle.net/hobojoe/1ce02bpe/
You can see that when using MVVM, the first group name is not displayed, only the following ones.
While working with regular JS widget initialization, everything is working as expected.
Am I doing something wrong? Is the a workaround that I can follow?
