如何使用angularjs验证动态创建的表单？

Question

Actually I'm creating the form dynamically and i have done two way binding also. Now I want to do the validation.

Requirements:

• 1. If i have value in field for (eg. Name: Raja) . If edit that value using $watch or $dirty we can check that modified or not. The same thing I want to get reverse also. Suppose I edited the value Raja to Raj and later again i'm adding the 'a' means Raja. If i give previous value again the status $dirty i should get false.
• 2. How can do this thing for whole form rather than giving each and every field.

Please help me anyone on this.

Here is my Plunker for simple example.

您应该使用类似$setPristine()东西http://plnkr.co/edit/1LJ5alREMhFXOqO8ZWbj?p=preview
