Karax: Change element value

[herdingSheep]

How do I change an element valut at runtime? I know changeName.text = n.values 
is incorrect but what should it be?
    
    
    include karax / prelude
    import karax / [vstyles]
    
    
    proc onNameEnter(ev: Event; n: VNode) =
        if n.value.strip() != "":
            changeName.text = n.values
    
    proc createDom(): VNode =
        result = buildHtml(tdiv):
            h1(id = "changeName"):
                text "Name will apear here."
            form:
                label(`for` = "fname"):
                    text "Enter Name:"
                input(type = "text", id = "fname", name = "fname",
                        onkeyupenter = onNameEnter)
    
    
    setRenderer createDom
    
    
    Run
