title: Kendo datepicker value method doesn't fire its own change event
body: <p>If I select date in Kendo UI datepicker with a mouse, my observer (binded viewModel) see the changes. 
  But if I set value of datepicker in code, like this:</p>
  
  <pre><code>$("#dateFromFilter").data("kendoDatePicker").value(todayDate);
  </code></pre>
  
  <p>the observer doesn't catch the event:</p>
  
  <pre><code>dateRangeViewModel = kendo.observable({
          selectedDateFrom: null,
          onChange: function (e) {
  // selectedDateFrom is not changing because datePicker change event don't work for this
          console.log("date: " + kendo.toString(this.get("selectedDateFrom"), "D"));      
          }
  });
  
  kendo.bind($("#dateFromFilter"), dateRangeViewModel);
  </code></pre>
  
  <p>Is it a correct behaviour? How to resolve the issue?</p>
