Can not click checkbox with element from by.repeater
<p>For some reason I can not click a checkbox with <code>by.repeater</code>. There are no errors. When viewing the browser, the checkbox is simply not getting checked. Any ideas? I would like to stay with <code>by.repeater</code> if possible. </p>

<pre><code>  this.modelChoices = function(rowNumber) {
    return element.all(by.repeater('model in vehicleCheckboxes.models'));
  } 

  checkboxes.modelChoices().get(0).click();
</code></pre>
