ASP.NET MVC局部视图不会调用我的Action

I just started building a small simple Website on ASP.NET MVC, in a page I am using a Partial view, the Partial View represents a simple Form which should be submitted on button click, and If I click the first Time it is submitted with success and does return my partial view with my validation Messages (if the content is invalid) but if I wish to try again the Action isn't called again. Any Idea?I just started building a small simple Website
