title: "swipe back" in ion-item after click on ion-option-button
body: <p>in an Ionic project I made a ion-list ion-items and these ion-option-buttons:</p>
  
  <pre><code>&lt;ion-list&gt;
       &lt;ion-item class="item " ng-repeat="exercise in exercises" on-double-tap="sendToChangeExercise"&gt;
  
              &lt;p&gt;&lt;h2&gt;{{exercise.exerciseName}}&lt;/h2&gt;&lt;/p&gt;
  
              &lt;p ng-repeat="(parameter, value) in exercise.parameters"&gt;
               {{parameter}}: {{value}} &lt;span ng-if="exercise.trainingData[parameter].length &gt; 0 "&gt;&lt;b&gt;&lt;i&gt;Eintrag im Trainingtagebuch: {{exercise.trainingData[parameter]}}&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;
              &lt;/p&gt;
         &lt;ion-option-button class="button button-calm"  ng-click="openModal(exercise.exerciseID)"&gt; Info &lt;/ion-option-button&gt;
         &lt;ion-option-button class="button button-energized"  ng-click="openModal(exercise.exerciseID)"&gt; Ändern &lt;/ion-option-button&gt;
              &lt;ion-option-button class="button button-balanced"  ng-click="didExercise(exercise.exerciseID)" ng-if="!exercise.done"&gt; Done &lt;/ion-option-button&gt;
        &lt;/ion-item&gt;
  &lt;/ion-list&gt;
  </code></pre>
  
  <p>Let's say I swipe left on an item. Then the buttons appear. I click on a button and it does what it's supposed to do. But the ion-item still is in this "swipe left" state. You know what I mean? Now I have to swipe right so that the buttons disappear.
  Is there anything so that I could automatically let the buttons disappear at the end of the JS functions?</p>
  
  <p>Thanks for help</p>
