Is there any callback function for change of Item values in GuideDropDownList in latest API?

[pulkitvashisth]

There is a elementValueChanged callback in GuideBridge API but none to check the change in Item values of GuideDropDown element. Is there any existing callback in the latest API or any other work around for performing this task.

elementValueChanged does not work for itemsChange
