C# “提交”按钮在asp.net mvc中不起作用

我有一个模型：

public class FormCreateModel
{
    public FormModel formInfo { get; set; }
    public FieldModel fieldInfo { get; set; }
    public InstitutionModel selectedInst { get; set; }
    public FormTypeModel selectedFormType { get; set; }
    public CategoryModel categoryInfo { get; set; }
    public List<InstitutionModel> institutions { get; set; }
    public List<FormTypeModel> FormTypes { get; set; }
}

当我提交按钮时，newform仍为空。。我调试了它，发现submit按钮没有触发或向newform发送值。我只在MVC呆了几天，请帮助我改变

<input id="btnSubmit" type="button" value="Submit" />

到

对于输入元素

类型

属性

的可能重复项，应使用

提交

而不是

按钮

public ActionResult createNewForm(FormCreateModel newForm)
{
    InstitutionManagement im = new InstitutionManagement();
    newForm.institutions = im.getInstitution();
    FormManagement fm = new FormManagement();
    newForm.FormTypes = fm.getFormType();
    return View("createNewForm", newForm);
}

<input id="btnSubmit" type="button" value="Submit" />

<input id="btnSubmit" type="submit" value="Submit" />
