I tried to move the working control from another page to this one and now it also doesn't work - weird....

@using Siriusware.Resources;
<ng-form name="editPaDSSForm">
    <div class="form-horizontal">
        <div class="row">
            <div class="form-group">

                               ng-hide="(form.editPaDSSForm.discPct.$error.max || form.editPaDSSForm.discPct.$error.min) && form.editPaDSSForm.discPct.$dirty">@Labels.percentage:</label>
                            <label class="field-validation-error control-label-error animate-show"
                                   ng-show="(form.editPaDSSForm.discPct.$error.max || form.editPaDSSForm.discPct.$error.min) && form.editPaDSSForm.discPct.$dirty">
                                @String.Format(Messages.dataRange, "-100", "100")
                            </label>

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

What may be responsible for working / not working?
