Corona widget.newButton passing data to function

I have scoured the documentation and google for a solution but none was found.

Simply: I want to pass data to a function, when a button is pressed. Issue: The buttons are dynamically created, so the data must be presented when the button is built.

The code looks like this;

    myButton = widget.newButton({
        x = width * 0.875,
        y = height * heightChange,
        width = width * 0.18,
        height = height * 0.09,
        defaultFile = "Assets/Images/button_up.png",
        overFile = "Assets/Images/button_down.png",
        onEvent = func_myFunction
    })

But I want to do something like;

    onEvent = func_myFunction("My Data")

or

    onEvent = func_myFunction, myData

neither of which work. Any ideas?

It's simple you just need to add an eventlistener to the end of your code so when it's clicked your data would execute.

myButton = widget.newButton({
    x = width * 0.875,
    y = height * heightChange,
    width = width * 0.18,
    height = height * 0.09,
    defaultFile = "Assets/Images/button_up.png",
    overFile = "Assets/Images/button_down.png",
    onEvent = func_myFunction
})
myButton:addEventListener("touch",onEvent);

I hope this fixes your problem.
