How to clear selected values in ui-select2

[salini11]

I have something like this

<select  ui-select2="{ allowClear: true}" ng-model="form_user_id" id="source" multiple="multiple">
    <option value="{{row.user_id}}" ng-repeat="row in user_data track by $index">{{row.name}} - {{row.mobile}}</option>
</select>

In some cases I need to clear the selected values. For that I cleared the ng-model form_user_id
$scope.form_user_id = [];
When I do that in my code, I can see the array is truncated, but the view still shows the items.
How can I clear the view?

I met this problem too, have you found any solutions? @salini11

You can use this code to clear selected. But i don't like.

$scope.form_user_id='';
$('#source').val(['']).trigger('change');
