[MouseArea] Button can't un-highlight

Hi all,

I have a problem need for your help. In my project, I use this code to highlight button when touching

function toggleImage(isPressed) { source = (isPressed ? focusSource : normalSource); }
onContainsMouseChanged: parent.toggleImage(containsMouse)

and the other button I using this code:

MouseArea
{
    onPressed: { parent.source = UIBridge.getImageSourceByName("active"); }
    onReleased: { parent.source = UIBridge.getImageSourceByName("inactive"); }
}

But there is a problem with my touchscreen. buttons are highlighted when I press but they aren't un-highlighted when I release my finger. Could you please support me to check this issue?

Thanks
