 <p>your form should be something like this</p> <pre><code>&lt;form&gt; &lt;label for='qpInputdata'&gt;No Selection&lt;/label&gt; &lt;input id="qpInputdata" class="form-control name="xCaasType" ng-model="fData.selection" type="radio" ng-value="true" value="no"&gt; &lt;label for='qpInputdata'&gt;Select This One&lt;/label&gt; &lt;input id="qpInputdata" class="form-control name="xCaasType" ng-model="fData.selection" type="radio" ng-value="true" value="selected"&gt; &lt;/form&gt; </code></pre> <p>now the model <strong>fData.selection</strong> will hold one of these two values "no","selected" according to the selected option</p>
