<p>
  text
  <select data-bind="options: optDiv, 
        value: ligaSelec,
        optionsCaption: 'Divison',
        event:{ change: $root.DivisionChanged}"></select>

</p>

var vm = {
  optDiv: ['Div1', 'Div2'],
  DivisionChanged: function() {
    alert('Div changed');
  },
  ligaSelec: ko.observable()
};

ko.applyBindings(vm);
