JQuery :: How To Get Text Of (Radio Buttons) Labels

I have a php-based form with radio-buttons with following labels - I've been trying to get the text-value of these labels, but I keep getting empty variables - it seems it doesn't pick up the value at all.

Here's some of the code:
<li><span class="radioinput"><input class="crirHiddenJS" id="this_pulje_
<?php echo $pulje['pv_ID']; ?>" type="radio" name="
<?php echo $pulje['p_subname']; ?>" value="
<?php echo $pulje['pv_ID']; ?>"></span><label for="this_pulje_
<?php echo $pulje['pv_ID']; ?>"><strong>
<?php echo $gametype; ?>, M: </strong>
<?php echo $pulje['pv_module']." <strong>S: </strong>".$pulje['pv_system']."
<strong>GM: </strong>".$pulje['pv_GM']; ?></label></li>

Which outputs something like this:
<li><span class="radioinput">
<input type="radio" value="47" name="pulje_2" id="this_pulje_47" class="crirHidden">
</span><label for="this_pulje_47" class="radio_unchecked">
<strong>R, M: </strong>Bergen 2192 <strong>S: </strong>Blue Planet v2
<strong>GM: </strong>Thor André Karstensen</label></li>

And then I have the following jQuerycode, which doesn't return anything:
var radioContent = $("#"+prevTarget+" :radio:checked").next('label').text();
As for the "prevTarget" it's being populated, because if I change the above to this:
var radioContent = $("#"+prevTarget+" :radio:checked").val();
It returns the value just fine. But for some reason it doesn't return the text from the label - and I don't really understand why. Test-page found here: [URL]
