RangeSlider onFirstChange non-existent property Error

[Argprstest]

i using rangeslider for my project in qml. My range slider codes is

RangeSlider {
            id: rangeSLider
        first.value:  0.0
        second.value: 1.0
        anchors.horizontalCenter: parent.horizontalCenter
        width: 275
        onFirstChanged: console.log("Change")
    }

When i run this codes i have an error. Error is

Cannot assign to non-existent property "onFirstChanged"

I want to change a text in parent qml file. So i think if use onFirstChange and onSecondChange functions, i can do it. But it did not work.

How can i do that ?

Hi @Argprstest

From Qt documentation of RangeSlider, i am not seeing any

onFirstChanged

http://doc.qt.io/qt-5/qml-qtquick-controls2-rangeslider.html

from where do you get it?

When i write "on" and press ctrl+space qtcreator suggest "onFirstChange".

i solved my problem by add "Connections" in my range slider. More details
