inconsistency output of selected-object on modal (ngDialog)

[luqeckr]

i'm using angcomplete-alt in modal using ngDialog

it seem the selected-object give me inconsistent output
if i select on existing founded result then it's outputing an object
but if i press the 'tab' key to move focus to next input element
then it only left with 'originalObject' with value of the input.

if i just use my mouse to move the focus, then it will have
a lot, title, description, and originalObject which contain the selected object
