how to set minimum value in spinbox (fuelux)

I'm trying to set minimum value in the spinbox component of fuelux.

I execute this code:

$('.spinbox').spinbox('min', 1);

but Firefox give me this error in (fuelux.min.js):

TypeError: g[b] is undefined
..."fu.spinbox",g=new c(this,h)),"string"==typeof b&&(d=g[b].apply(g,e))});return v...

Can anyone help me ?

spinbox code: http://getfuelux.com/javascript.html#spinbox-examples

i have debug the core plugin and found what is happen:

in the demo page of fuel ux, the guide provide this code:

<div class="spinbox" data-initialize="spinbox" id="mySpinbox">
      <input type="text" class="form-control input-mini spinbox-input">
      <div class="spinbox-buttons btn-group btn-group-vertical">
        <button type="button" class="btn btn-default spinbox-up btn-xs">
          <span class="glyphicon glyphicon-chevron-up"></span><span class="sr-only">Increase</span>
        </button>
        <button type="button" class="btn btn-default spinbox-down btn-xs">
          <span class="glyphicon glyphicon-chevron-down"></span><span class="sr-only">Decrease</span>
        </button>
      </div>
    </div>

but there is a bug in the plugin when data-initialize="spinbox" is present.

So use the html code above without data-initialize="spinbox" and initialise the componenent with your prefered options like this:

$('#mySpinbox').spinbox({
  'value': 1,
  'min' : 1
});
