Alloy ListView with Switch in template

I have a simple ListView using Alloy xml. It contains a switch (checkbox) and a label. How can i get all the items the user has marked (or the underlying data-index or something else) ?

I am using Titanium 3.x anddeploying on Android

simple sample:

<ListView id="myList" defaultItemTemplate="myTemplate">
    <Templates>
        <ItemTemplate name="myTemplate">
            <Switch bindId="checked" value="false"/>
            <Label bindId="title" left="40dp"/>
        </ItemTemplate>
    </Templates>
    <ListSection headerTitle="A Section">
        <ListItem title:text="A Title one" checked:value="false"/>
        <ListItem title:text="A Title two" checked:value="false"/>
        <ListItem title:text="A Title three" checked:value="false"/>
    </ListSection>
</ListView>
