How can i change the background color of an listviewrecord dynamically when selected?

When a listviewrecord is clicked, i'm showing additional data in a seperate window. I want to change the backgroundcolor of the selected listitemrecord. This way i want to show which item was selected.

I know there is a selectedBackgroundColor attribute, it not doing what i want. This attribute is using backgroundcolor only when you actively select the item, on releasing your finger the color disappears again.

see my template below

<Templates>
                <ItemTemplate name="template">
                    <View class="recordcontainer">
                        <Label bindId="businessName" id="businessName" class="topline" />
                        <View id="adrescontainer">
                            <Label bindId="adres" id="adres" class="bottomline" />
                            ,
                        </View>
                    </View>
                </ItemTemplate>
            </Templates>
 
in my controller within the handler of itemclick event
 var item = $.mainsection.getItemAt(eo.itemIndex);
