JavaScript Pass a (new class) as a parameter

How do I pass a (new class) as a parameter to a button component without the function executing without click event is triggered.

class cDevice {
    new() { 
        //something here;
    }
}

device: {
    // the (new cDevice).new() is what I want to pass.
    createNew: function () { (new cDevice).new() }, 
}

This is the parameter will be used for, execute (new cDevice).new() when button click event is triggered.

"<button onclick=" + device.createNew + ">new</button>"

Thank you!
