.NET MVC Ajax Form保留旧的输入值 - 如何更新模型的值？

I have a properly working ajax form in my MVC3 application except for one caveat. After I submit the form and get the result, even though the passed in model has a different value for the input (Amount in the example below) the old value still shows up on the screen. I attribute this to the value being saved in the DOM and overriding/preventing the new value from the model. There are various ways to fix this by running a javascript function on one of the form events.I have a properly working ajax form in my MVC3
