Kendo UI AutoComplete datasource transport reads only once - autocomplete

Question

I'm becoming crazy with Kendo UI AutoComplete component. I'm using my own functions to access data with jQuery, so I have to set the AutoComplete dataSource.transport.read as a function. The code is something like this.
minLengthAtocomplete = 3;
$('#autocomplete').kendoAutoComplete({
minLength : 3,
filter : "contains",
dataValueField : "key",
dataTextField : "value",
dataSource : new kendo.data.DataSource({
transport : {
read : _OnTransportRead
},
schema : {
/* object schema */
}
})
});
function _OnTransportRead(e) {
var text = $.trim(e.data.filter.filters[0].value);
if (text && text.length >= minLengthAtocomplete) {
_GetUsers(
text,
function onSuccess(data) {
var users = [];
/* sets users with info in data */
e.success(users);
},
function onError(error) {
/* stuff with error */
}
);
}
}
function _GetUsers(userName, onSuccess, onError) {
/* Ajax to get users from DB */
}
This code runs perfectly, but dataSource.transport.read is called only the once. I do a first search with the text 'michae' and AutoComplete component runs its dataSource.transport.read as expected. Then, I add a one more letter to search for 'michael', and dataSource.transport.read is never called again. Is so frustrating!
I tried using autoSync dataSource property, manual dataSource Sync, set new dataSource objects on AutoComplete dataBound, but no luck.
What am I doing wrong? What am I forgetting?
Thanks in advance.

You should enable serverFiltering in order for the data source to make requests every time.
$('#autocomplete').kendoAutoComplete({
    minLength : 3,
    filter : "contains",
    dataValueField : "key",
    dataTextField : "value",
    dataSource : new kendo.data.DataSource({,
serverFiltering: true,
        transport : {
            read : _OnTransportRead
        },
        schema : {
            /* object schema */
        }
    })
});
