dropdown list in konckout is empty

[nader....@telia.com]

I have the follwing knockout code but the resulting dropdownlist in html page dose not show anything.

<script type='text/javascript' src='knockout-3.3.0.js'></script>

<p>

Behandlingsmetod: 

<select data-bind="options: behandlingsmetod, value: selectedbehandling,

              optionstext:'selectedbehandling',

                       optionsCaption: 'Choose...'" size="5" multiple="true"></select>   

 </p>

<script>

function BehandlingViewModel()

{

  var self = this;

   self.förnamn = ko.observable();

   self.lastName = ko.observable();

   self.personnummer = ko.observable();

   self.behandlingsmetod =  ko.observableArray(['first', 'second', 'third']);

   self.selectedbehandling = ko.observable();

    

};

ko.applyBindings(new BehandlingViewModel());

</script>

The options binding will bind each object in the array. the other parameters such as optionstext: 'selectedbehandling' are treated as properties on the object.

if you removed, the optionstext and value, things will start working.

here is a jsfiddle link with a basic working.
