title: uncheck the checkbox in checkbox list in AngularJS
body: <p>I want to uncheck the checkbox from the list of checkbox depending upon the condition.Checkboxes are generated from the ng-repeat</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;li ng-repeat="col in columns"&gt;
      &lt;span class="inputH"&gt;
           &lt;input type="checkbox" value="col.name"   ng-if="col.default === true" checked ng-click="onColSelect(col.name,$event)" id="column_{{$index}}"&gt;
           &lt;input type="checkbox" value="col.name"  ng-if="col.default === false" ng-click="onColSelect(col.name,$event)" id="column_{{$index}}"&gt;
      &lt;/span&gt;
      &lt;span class="textH"&gt;{{ 'leadOpportunityHeader.' + col.name | translate }}&lt;/span&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>while cliking each checkbox, I check some condition. If this condition is true then I uncheck the same checkbox.
  My question is is it possible to uncheck the checkbox without using <code>ng-model</code>?
  If its not possile then I need to know how will I do this with the help of ng-model</p>
