Text clickable in repeater

You just need to create the click with the context event, because it is a repeater, like this:

$w.onReady(() => {
    $w("#textRepeater").onClick((event, $item) => {
        $item = $w.at(event.context) //This creates the context (the item inside the repeater)
        $item("#textRepeater").text = "Clicked!" //This changes the text in the context
    })
})
