Display the fullname without clicking on the button in this tutorial

Question

Hello,
I am referring to this tutorial : Zeeshan Baig's Blog: Calling PL/SQL Procedure and Function in Oracle ADF application
1) I would like the fullname to be displayed automatically after the employee id is input ,without having to click the getEmpFullName button.
2) I would like to copy the fullname value to an entity attribute and save in db .
Is that possible please ? Thanks.

Thanks  931325 , I want to use the tutorial link that you sent me .
Step1 : Define the application module method in respective page definition as shown in below screen shot 
Step2: Write the below code in backing bean to invoke application module method
Note : I have done step 1 , my method is already in page definition. How do you implement step 2 . 
public void ot2_attributeChangeListener(AttributeChangeEvent attributeChangeEvent) {
FacesContext facesContext = FacesContext.getCurrentInstance();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, "#{bindings}", Object.class);
BindingContainer binding= (BindingContainer)valueExp.getValue(elContext);
OperationBinding operationBinding=binding.getOperationBinding("createCurrentCustomerRow");
// Set the Input parameters to the operation bindings as below
operationBinding.getParamsMap().put("pCustomerID", "100"); 
// Invoke the Application module method
operationBinding.execute();
// Get the result from operation bindings
Object obj =operationBinding.getResult()
Thanks
