[kamal0808]

Description

The function tied to ac-selected-item-change loads when the DOM loads, even when there is no change in the selected item. This happens in case only if there is a preselected item in ac-selected-item during DOM load.

Expected behaviour

The functionality tied to ac-selected-item-change should check first if there is a value being assigned in ac-selected-item. If ac-selected-item is undefined at first, then only ac-selected-item-change function should execute.
