Datepicker doesn't work with bootstrap validation

The required attribute is ignored and client side validation by bootstrap does not take place.
<input type="text" name="due_date" class="form-control" id="inputDueDate" required>

Do you have any solution for this bug ?

The solution i found is to remove the readOnly attribute from the input using jquery after setting the datePicler. ( .prop(readOnly, false).
