    var tag = $(this);
   alert(tag.attr('data-test').split('\'')[1]);
})

$(".click").click(function(){
    var pattern = /@[a-z]{3}/i
    var text = $(this).attr('data-test')

    alert(text.match(pattern ));
})

See the fiddle here: http://jsfiddle.net/Xr7bw/4/

But it all depends on the pattern, this one just matches and "@" with three characters behind it in the range [a-z]... If you can be more precise with what possible values will be, we can be more precies with capturing them

One way:

var text = $(this).data("test");
alert ( text.match(/^.*\('(.*)\s*'/)[1] );

You could just split on the single quote character and take the second value returned:

$(".click").click(function(){
    var text = $(this).data('test').split("'")[1];
    alert(text);
});

Working Demo
