[gewaking]

$("#MyList").dropdown({
onChange: function(value, text) {
console.log("a");
}
});

<div id="MyList" class="ui dropdown item"> Export <i class="dropdown icon"></i>
  <div class="menu">
    <div data-value="1" class="item">Item 1</div>
    <div data-value="2" class="item">Item 2</div>
  </div>
  <input type="hidden" name="item">
</div>

Pass it in as at init as true
