title: angular ng-select how to set selected value by using template expression
body: <p>angular ng-select how to set selected value by using a template. For example something like this,</p>
  <pre><code>&lt;ng-select
            [options]=&quot;[{label : &quot;first&quot;, value : &quot;1&quot;}, {label : &quot;second&quot;, value : &quot;2&quot;}]&quot;
            **[value]=&quot;'1'&quot;**
            [multiple]=&quot;false&quot;&gt;
  &lt;/ng-select&gt;
  </code></pre>
  <p>I am using angular2-select npm package. I would like to have the Input attribute do the task instead of ngModel.</p>
