Bootstrap button not showing as selected on post back.

When my model comes back is not valid and the page reloads my radio button  that is selected does not visually show as selected. What can I do to correct this problem?

  <div id="radios">
            <div class="form-group">
                <div class="btn-group col-md-offset-1" data-toggle="buttons">
                    <label class="btn btn-default btn-lg col-md-1">
                        @Html.RadioButtonFor(model => model.SetDollarAmount, "25", new { id = "Amount25" }) $25
                    </label>
                    <label class="btn btn-default btn-lg col-md-1">
                        @Html.RadioButtonFor(model => model.SetDollarAmount, "50", new { id = "Amount50" }) $50
                    </label>
                    <label class="btn btn-default btn-lg col-md-1">
                        @Html.RadioButtonFor(model => model.SetDollarAmount, "100", new { id = "Amount100" }) $100
                    </label>
                    <label class="btn btn-default btn-lg col-md-1">
                        @Html.RadioButtonFor(model => model.SetDollarAmount, "250", new { id = "Amount250" }) $250
                    </label>
                    @Html.LabelFor(model => model.Amount, new { @class = "control-label col-md-4" })
                    <div class="col-md-2">
                        @Html.TextBoxFor(model => model.Amount, new { @class = "form-control input-large" })
                        @Html.ValidationMessageFor(model => model.Amount)
                    </div>
                </div>
            </div>
        </div>

This works fine:
[HttpPost]
        public ActionResult Index(EEBootstrap.Bootstrap item)
        {
            ePIPDAPEntities entity = new ePIPDAPEntities();
            var query = entity.Bootstraps.FirstOrDefault();
            query.SetDollarAmount = item.SetDollarAmount;
            if (!ModelState.IsValid) {
           
                entity.SaveChanges();
            }
            return View(db.Bootstraps.FirstOrDefault());
        }
