code for change Slider Range value

code for change Slider Range value

Hi to All,

I'm able to read the value of an range/slider (single value) but have not idea of how to put/set/change the Value.

<form >
    <label for="wait">Wait minutes:</label>
    <input type="range" name="wait" id="wait"  min="1" max="60" step="1">
    //btw same situation if add value="10" or so
</form>

//works, get the value changed by the user
wait = $('#wait').val();


$('#wait').val("11");            //no works
$('#wait').val(11);            //no works
$('#wait').slider('refresh');  //even with or without this

tried to using other variants, no luck:
$(input[name='wait']).val(cfgMin);
$('#wait').prop('val','8');
$("input[type=range]").val("6");

I've read dozens of references but none helpful, hope yours have better eyes 

Thanks!
