Bootstrap Datepicker not displaying correctly

Question

Hi Ive put in a bootstrap date picker on my asp.net mvc form. Ive set it up so it starts displaying years from a decade.

But the date picker only displays the years as one longer string, its functional though

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/bootstrap")
<script type="text/javascript">
    $("#DateOfBirth").datepicker({
        format: "dd/mm/yyyy",
        startDate: "-120y",
        endDate: "-10y",
        startView: 2,
        calendarWeeks: true,
        defaultViewDate: { year: 1975, month: 01, day: 01 }
    });
    </script>
    }

Helper in view

<div class="row">
    <div class="col-md-3 col-md-offset-1">
        @Html.LabelFor(model => model.DateOfBirth, htmlAttributes: new { @class = "control-label" })
        @Html.EditorFor(model => model.DateOfBirth, new { htmlAttributes = new { @class = "form-control", placeholder = "01/12/80" } })
        @Html.ValidationMessageFor(model => model.DateOfBirth, "", new { @class = "text-danger" })
    </div>
</div>

Thanks
