How to reresh dropdown after new data from odata service "READ"

Hy,

I'am new in the fiori business and i'am struggling with the binding principles.

I created a combox in my XML view with a binding to my odata that has bin loaded by my WEBIDE. I get my list in my dropdown. So far so good but i want to refresh my list after an action by calling the backend again with a parameter. I get a return with different data, but i don't succeed in binding those new items to my drop down. I scanned in my opinion the hole internet but can't find a proper solution.

XML ( view1.xml ) :

<Combobox

id = "expenseID"

items = "{/ExpenseTypes}"

<core:Item key = "{ExpenseTypeID}" tekst = "{Description}"/>

<Combobox>

JS :

sap.ui.controller("view.view1",{

changeExpenseTypes: function(e) {

var model = this.getView().getModel();

var sUrl = "/ExpenseTypes?search=2";

model.read(sUrl, null, null, false, function(data, reponse) {

console.log('success');

console.log(data);

return data; });

}

});

When i call method changeExpenseTypes , i load my allready know model, calling my odata service ExpenseTypes , got a return of 5 new records and then i don't know what to do next to see those new records in my drop down.

Thanks in advance for your help or suggestions  !!

Greetings

Jonas
