I made some changes:

<ng-form name="editPaDSSForm">
    <div class="form-horizontal">
        <div class="row">
            <div class="form-group">

                <div class="col-xs-6">
                    <label class="control-label"
                           ng-hide="(form.editPaDSSForm.maxDaysLocal.$error.max || form.editPaDSSForm.maxDaysLocal.$error.min) && form.editPaDSSForm.maxDaysLocal.$dirty"
                           title="@Messages.maxAgeLocalSalespoint">@Messages.maxAgeLocalSalespoint</label>
                        <label class="field-validation-error control-label-error animate-show"
                               ng-show="(form.editPaDSSForm.maxDaysLocal.$error.max || form.editPaDSSForm.maxDaysLocal.$error.min) && form.editPaDSSForm.maxDaysLocal.$dirty">
                            @String.Format(Messages.mustBeBetweenXandY, Messages.maxAgeLocalSalespoint, "1", "45")
                        </label>

                        <input type="number" name="maxDaysLocal"
                               id="maxDaysLocal"
                               min="1" max="45"
                               ng-model="currentPrefs.loclccdays"
                               class="form-control"
                               placeholder="0"
                               data-sm:number data-accuracy="0">


                    </div>
                </div>
            </div>
        </div>
 </ng-form>

The above is not working :(

And this works fine - do you see any difference?

<div class="col-lg-3 col-md-6">
                                <div class="format-label">
                                    <label class="control-label" 
                                           ng-hide="(form.editSpecialGeneralForm.discPct.$error.max || form.editSpecialGeneralForm.discPct.$error.min) && form.editSpecialGeneralForm.discPct.$dirty">@Labels.percentage:</label>
                                    <label class="field-validation-error control-label-error animate-show" 
                                           ng-show="(form.editSpecialGeneralForm.discPct.$error.max || form.editSpecialGeneralForm.discPct.$error.min) && form.editSpecialGeneralForm.discPct.$dirty">
                                        @String.Format(Messages.dataRange, "-100", "100")
                                    </label>
                                </div>
                                <div class="input-group">
                                    <input class="form-control percent-icon" id="discPct" max="100" min="-100"
                                           name="discPct"
                                           placeholder="0"
                                           ng-model="currentSpecial.discPct" type="number"
                                           data-sm:number data-accuracy="0">
                                    @*<span class="input-group-addon">%</span>*@
                                </div>
                            </div>
