Widget-sliders are not independently of each other

Apps & Services HABPanel

Hi,
I have some sliders in my panel. When I change one of them the others change with.

      <div class="switch btn-group slider-leftborder"
           ng-init='model={"name": "North", item: "IntensityNorth", "hidelabel": true, "hidepointer": true, "hidelimits": true }'>
        <widget-slider ng-model="model" style="width: 100%; margin-left: -10px; display: block;"></widget-slider>
      </div>

      <div class="switch btn-group slider-leftborder" 
           ng-init='model={"name": "South", item: "IntensitySouth", "hidelabel": true, "hidepointer": true, "hidelimits": true }'>
        <widget-slider ng-model="model" style="width: 100%; margin-left: -10px; display: block;"></widget-slider>
      </div>

I am afraid not to understand something important.
Greetings
