I am writing a web page for the mobile use, and I add a reset button to reset radio button but it not work. I have try to solve in many way, like

```
$('select#qty1 option').attr('selected', false);

$('select#qty1 option').removeAttr('selected');

$('select#qty1').children('option').removeAttr('selected').filter(':nth-child(1)').attr('selected', true);

$('select#qty1').attr('selectedIndex', -1);

```

but all of them do not work.

**Radio button**

```
<tr>
    <td><a href='#myPopup' data-rel='popup' class='ui-btn ui-shadow ui-corner-all ui-icon-info ui-btn-icon-notext' data-position-to='window'>info</a></td>
    <td>Pizza</td>
    <td>$100</td>
    <td>

        <select type='radio' data-native-menu='false' name='qty1' id='qty1'>

            <option value='0'>0</option>
            <option value='1'>1</option>
            <option value='2'>2</option>
            <option value='3'>3</option>
            <option value='4'>4</option>
            <option value='5'>5</option>

        </select>
    </td>

</tr>

```

**Reset button**

```
<input id="reset1" type="button" value="Reset"> 

```

**script**

```
$("#reset1").click(function(){
    $('select#qty1').attr('selectedIndex', -1);
});

```
