How to change control from other control in mvc

Hi,

I've MVC app with  text field and I want that when the user enter some text on it it will change the drop down selected value,

How should I do that ?

Example will be very helpful

This is the text field and for example when you type aaa I want that the drop down will have aaa selected

for example the drop down contain aaa bbb ccc etc

var tF = new sap.ui.commons.TextField({

  liveChange: [oController.onChange, oController]

  });

I saw the last example here but its not helpful since this example is not using  MVC

DropdownBox - SAPUI5 Demo Kit

I need somehow in the live change of the text field do the drop down logic to change the selected value
