While Loop to Set CasperJS "then ()" Steps

I am trying to check the visual state of several buttons - hover, click, focus - and was looking for a way not to copy basically the same command casper.then()again and again. I thought I could do it in a simple loop.

I made a small array (currently) of 5 buttons and while-looped through them I added CasperJS steps for each of the states that I would like to write. Unfortunately, only the last of the steps is actually performed.

I read a few posts about the loop, but all of them seem to include links to a link on a page or some other script that doesn't seem to match what I'm looking for.

Maybe I'm just tight? Code below ...

casper.thenOpen( 'docs/buttons/test.html' );

var buttonStyles = [
    { selector: '.grey0', title: 'Button - Grey 0' },
    { selector: '.grey25', title: 'Button - Grey 25' },
    { selector: '.grey50', title: 'Button - Grey 50' },
    { selector: '.grey75', title: 'Button - Grey 75' },
    { selector: '.grey100', title: 'Button - Grey 100' },
];

while (buttonStyles.length > 0) {

    buttonStyle = buttonStyles.pop();

    casper.then(function(){
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title);
    });

    casper.then(function(){
        this.mouse.move(buttonStyle.selector);
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title + ' - Hover');
    });

    casper.then(function(){
        this.mouse.down(buttonStyle.selector);
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title + ' - Down');
    });
}

casper.test.done();

"casper.repeat" :

casper.thenOpen( 'docs/buttons/test.html' );

var buttonStyles = [
    { selector: '.grey0', title: 'Button - Grey 0' },
    { selector: '.grey25', title: 'Button - Grey 25' },
    { selector: '.grey50', title: 'Button - Grey 50' },
    { selector: '.grey75', title: 'Button - Grey 75' },
    { selector: '.grey100', title: 'Button - Grey 100' },
];

var curIndex = 0;

casper.repeat(buttonStyles.length, function() {
    buttonStyle = buttonStyles[curIndex];
    casper.then(function(){
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title);
    });
    casper.then(function(){
        this.mouse.move(buttonStyle.selector);
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title + ' - Hover');
    });
    casper.then(function(){
        this.mouse.down(buttonStyle.selector);
        phantomcss.screenshot(buttonStyle.selector, buttonStyle.title + ' - Down');
    });
    curIndex++;
});

casper.test.done();
