Sharepoint javascript get current list item

Good Day.

I've some script which displays a list items:

var siteUrl = '/Test';

function retrieveListItems() {

    var clientContext = new SP.ClientContext(siteUrl);
    var oList = clientContext.get_web().get_lists().getByTitle('bills2');
  //var CustomDate = DateTime.Now;
  //alert(CustomDate);
            //var strCustomDate  = SPUtility.CreateISO8601DateTimeFromSystemDateTime(CustomDate);        
    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml('<View><Query><Where><Geq><FieldRef Name=\'ID\'/>' +
        '<Value Type=\'Number\'>1</Value></Geq></Where></Query><RowLimit></RowLimit></View>');
//camlQuery.set_viewXml('<View><Query><Where><Geq><FieldRef Name=\'data\'/><Value Type=\'DateTime\'>2013-06-21</Value></Geq></Where></Query></View>');
   
    this.collListItem = oList.getItems(camlQuery);
       
    clientContext.load(collListItem);
       
    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));       
       
}

function onQuerySucceeded(sender, args) {

    var listItemInfo = '';

    var listItemEnumerator = collListItem.getEnumerator();
       
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
        listItemInfo += '\nID: ' + oListItem.get_id() +
            '\nTitle: ' + oListItem.get_item('Title')+
            '\n1: ' + oListItem.get_item('_x0031_')+
            '\n2: ' + oListItem.get_item('_x0032_');
    }

    alert(listItemInfo.toString());
}

function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

But, if I use list filter, I will got all items of list. And I need get only filter items of list Sharepoint.

What I donot correctly?
