AngularJS ui-select dropdown default value

I am using angular ui-select for drop down. How can I set a default value for the drop down value?

<h3>Selectize theme</h3>
  <p>Selected: {{country.selected}}</p>
  <ui-select ng-model="country.selected" theme="selectize" ng-disabled="disabled" style="width: 300px;">
    <ui-select-match placeholder="Select or search a country in the list...">{{$select.selected.name}}</ui-select-match>
    <ui-select-choices repeat="country in countries | filter: $select.search">
      <span ng-bind-html="country.name | highlight: $select.search"></span>
      <small ng-bind-html="country.code | highlight: $select.search"></small>
    </ui-select-choices>
  </ui-select>

The snippet is from plnkr.co. Currently the dropdown just sowing default Select or search a country in the list... But i need to pass a value from controller. Lets say $scope.default = {"name":"Decard"}

Thanks!!

EDIT

This question is similar to This one but involving json return format of data.

You can initial your ng-model to the default country object in your controller as following:

 $scope.country = {};
 $scope.country.selected = {name: 'Albania', code: 'AL'};

Then use "ui-select-match" to set the default value like this:

<ui-select ng-model="country.selected" theme="selectize" ng-disabled="disabled" style="width: 300px;">
<ui-select-match placeholder="Select or search a country in the list...">{{ $select.selected.name }}</ui-select-match>
<ui-select-choices repeat="country in countries | filter: $select.search">
  <span ng-bind-html="country.name | highlight: $select.search"></span>
  <small ng-bind-html="country.code | highlight: $select.search"></small>
</ui-select-choices>
</ui-select>
