title: Uncheck radio buttons in react
body: <p>I think its a very silly doubt but I am stuck in this..
  I have multiple radio buttons and I want to uncheck all the radio buttons as soon as I click the other radio button.
  How can I achieve it in react?</p>
  
  <pre><code>var options = [{id:1,nm:"Appointment fixed"},{id:2,nm:"Call later"},{id:3,nm:"Wrong number"},{id:4,nm:"Don't call again"},{id:5,nm:"Call later"}];
  {options.map((item,i) =&gt; {
                       return (
                          &lt;div onChange={(i)=&gt;this.callOptions(i)}&gt;
                             &lt;label className="radio-inline"&gt;&lt;input type="radio" value={i} ref={'ref_' + i} value={item.id}/&gt;{item.nm}&lt;/label&gt;
                          &lt;/div&gt;
                        )
                    })}
  </code></pre>
