md-autocomplete doesn't show li items text - angularjs

Question

I have a md-autocomplete field:
<md-autocomplete md-selected-item="videoInfo.lineUp[1]" md-items="item in searchQuery(searchText)" md-search-text="searchText" md-item-text="item.display"></md-autocomplete>
I populate md-items with
$scope.searchQuery = function (searchText) {
var users = [];
angular.forEach($scope.users,
function (value, key) {
// value = user object
// key = userId
var dN = value["display_name"];
if (dN) {
var obj = {};
obj[key] = value;
obj["display"] = dN;
if (dN.toLowerCase().indexOf(searchText.toLowerCase()) !== -1) {
users.push(obj);
}
}
});
return users;
}
It working in the sense that I can type in the input field and suggestions are loaded, however the dropdown is empty, i.e. it doesn't show display_name as I would have expected. When I select one of the options, the display_name of the selected item does show up in the input field. Any ideas what I could be doing wrong?

You need to define how you display information in the dropdown within the <md-autocomplete> tag. Here's an example - CodePen
Markup
<div ng-controller="AppCtrl as vm" ng-cloak="" ng-app="MyApp">
<md-autocomplete flex
md-selected-item="text"
md-no-cache="true"
md-items="item in vm.items()"
md-min-length="0">
<span id="autocompleteText" md-highlight-text="searchText">{{item}}</span>
</md-autocomplete>
</div>
