Use Alloy infiniteScroll ?

I'm trying to use the Infinite Scroll widget but I can not get it to work (the action does not trigger at the end of my table)

InfiniteScroll on Github

The documentation say to add this in a table view :

<TableView id="table">
  <Widget id="is" src="nl.fokkezb.infiniteScroll" onEnd="myLoader" />
</TableView>

<Collection src="book" />
    <Window class="container">
        <TableView dataCollection="book" >
            <TableViewRow title="{title}" />
            <Widget id="is" src="nl.fokkezb.infiniteScroll" onEnd="myLoader" />
        </TableView>
    </Window>
