79 +Now we have a simple form to update the string. The only thing we need to do is to implement the //updateString// method. Open the **Main.java** file and add the following code:
80 +
81 +{{code language="java" theme="Eclipse"}}
82 +
83 + public WOActionResults updateString() {
84 + return null;
85 + }
86 +
87 +{{/code}}
88 +
89 +Run the project again, and update the string in the text field. It's now 100% dynamic! Since we added a setter for the variable a couple of steps before, you don't need to set the string in the updateString method, that's the power of bindings.
