Scriptui multiple buttons action

Question

I want to create a dialog consisting of multiple buttons. As a result I want value which button was pressed by user.
The script (shortened to problematic part):
// I'm looping through elements on layer 'warstwa' from kolorStart to kolorStop, 'k' is used for number buttons
                    for (i = kolorStart, k = 0; i <= kolorStop; k++, i++) {
                              myButton[k] = myButtonGroup.add ("button", undefined, warstwa.pageItems[i].contents);
                              myButton[k].label = warstwa.pageItems[i].contents;
                              myButton[k].onClick = function () { wybranyKolor = myButton[k].label; myWindow.close(); }
The result:
but buttons don't work, wybranyKolor returning 'undefined'. If I change "wybranyKolor =  myButton[k].label" to "wybranyKolor =  myButton[k-1].label" I get proper answer but it is the same for all buttons so it looks that all buttons have the same acion assigned. How to get each button to has unique name which can be passed to variable?
Propably I can achive the same with radio buttons' list but with buttons it is one click less for the user.

sorry I don't understand your new question,
you need this
myButton[k].label = warstwa.pageItems[i].contents;
you don't need this one
myButton[k].onClick = function () { wybranyKolor = myButton[k].label; myWindow.close(); }
replace with
myButton[k].onClick = function () { wybranyKolor = this.label; myWindow.close(); }
