title: Kendo dropdownlist not executing ng-focus binded function
body: <p>I have this dropdown defined on template </p>
  
  <pre><code>&lt;select id="{{vm.field.id}}"
          kendo-drop-down-list
          k-data-source="vm.field.options"
          k-data-value-field="'code'"
          k-data-text-field="'description'"
          k-index="vm.selectedIndex"
          k-ng-model="vm.field.value"
          k-value-primitive="true"
          k-options="vm.field.config"
          ng-blur="vm.unfocusField()"
          ng-focus="vm.focusField()"
          k-on-change="vm.onValueChange()"&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>As you can see, I have ng-focus set (targeting to vm.focusField() function), this event is rightly applied and function triggered when I focus field by clicking directly on it with the mouse. But when this field is focused by tabbing (tab keyboard) from a previous field on form list. When I press tab, the field gets "focused" since in html the class 'k-state-focused' is added to element and I can use the up and down cursor buttons to change dropdownlist value, BUT, the ng-focus binded function is not executed. In resume this ng-focus words focusing by click, but not executed focusing by tab keyboard. I proved this function is not being called in this situation using developer tools and breakpoints on binded function</p>
