Hi,

this basic code adds items to the end of an observable list. How do i add items to the beginning of the list ?

<App Theme="Basic">
<JavaScript>
    var Observable = require("FuseJS/Observable");
    var item = Observable();
    var i = 0;

    function addItemBottom(){
        i = i + 1;
        item.add({text: i.toString()});
    }

    function addItemTop(){
        i = i + 1;
        // ???????
    }

    module.exports = {

        addItemBottom: addItemBottom,
           addItemTop: addItemTop,
           item: item

    }
</JavaScript>

<StackPanel>
    <Button Text="Add botom" Clicked="{addItemBottom}"/>
    <Button Text="Add top" Clicked="{addItemTop}"/>

    <Each Items="{item}">
        <Panel Margin="0,5,0,5" Background="#f0f">
            <Text Value="{text}"/>
        </Panel>
    </Each>
</StackPanel>
