Work with Razor class library

[xuechao0622]

why my Save button does not work. I can not find any post request after I click the save button.. And the OnPostAsync method does not trigger,too. This file is in a Razor class library. All the methods except the savebutton(or onpostasync) works fine.

@page
@using Volo.Abp.AspNetCore.Mvc.UI.Bootstrap.TagHelpers.Modal
@using Microsoft.Extensions.Localization
@using ITDog.Localization
@using ITDog.System.Area.Localization
@inject IStringLocalizer<ITDogResource> L
@model ITDog.System.Pages.Areas.Localization.Pages.EditModalModel
@{
     Layout = null;
}<abp-dynamic-form abp-model="LangInfo" asp-page="/Localization/EditModal">
    <abp-modal>
        <abp-modal-header title="@L["UpdateLangInfo"].Value"></abp-modal-header>
        <abp-modal-body>
            <abp-input asp-for="Id" />
            <abp-form-content />
        </abp-modal-body>
        <abp-modal-footer buttons="@(AbpModalButtons.Cancel|AbpModalButtons.Save)"></abp-modal-footer>
    </abp-modal>
</abp-dynamic-form>
