I'm using angular-ui to make a multi-select drop-down.
when I use "track by $index" when I type in search input, the item that I search for will be copied for example if I want to search for "south korea" it will be copied with any keypress and when I use "track by data.id" and it shows this error: "Duplicates in a repeater are not allowed" and it won't search properly.
my code is here
I appreciate any help
Because every time the search is inputted, it request the jsondata
Maybe it's a problem here
refresh="getData($select.search)"
