onClick function in the buttons array

[nikkiejohns]

I don't know if this is the right place to post this but i liked your plugin, i find it stylish and all but i have an issue with the onClick parameter of the button element in the buttons array.

Here:

buttons: [{
        text: 'OK', 
        val: 'ok',
        eKey: true, 
        addClass: 'btn-light-blue btn-square',
        onClick: function(argument) {
                    console.log(argument);
                    alert('Look in console!');
                  }
        }, ]

Is the function supposed to be triggered after a click on the button ? If so, why any action i put in the body of the function doesn't work (even the alert in the example) ? And what's this "argument" parameter of the function ? Is it mandatory ? What value is it supposed to contain ? I've carefully read the readme file but it still isn't clear enough.

Since the main purpose of such modals is to perform an action when a button is clicked, i find this very disturbing and i would be very grateful if you could explain to me what i'm missing here.
