Checkbox isn't taking action til my cursor leaves it

I have about ten check boxes that each implement different functions. I am trying to make one master checkbox that will a) check all 10 checkboxes; b) implement the functions in each

I have gotten one to work but for some reason, when I check it, the others aren't checked until I move my mouse off of the master checkbox (after checking it). Bizarre, right? Here is the code for the master checkbox and the sub-checkboxes. (I have to warn you that I am a little new to javascript and it's possible that this is terribly written. Advice in that direction also welcome.)

/*change all buttons of a single genre*/
$("a[id^="+genre+"_]").attr("class",  modereplacement+"Button" + " showButton");
$("a[id^="+genre+"_]").attr("onClick", function(index, currentValue){ return currentValue.replace(mode, modereplacement) ; }); 
$("#"+"all_"+genre+'_cur').attr("onClick",function(index, currentValue){ return currentValue.replace(mode, modereplacement) ; }); 

/*check all checkboxes*/
if (category =='All')
{
    $("#"+"alls_cur").attr("onClick",function(index, currentValue){ return currentValue.replace(mode, modereplacement) ; }); 
    for (var i = 0 ; i < 13 ; i++)
    {
        /*change individual buttons*/
        var currentgenre = allgenre[i]; 
        $("a[id^="+currentgenre+"_]").attr("class",  modereplacement+"Button" + " showButton");
        $("a[id^="+currentgenre+"_]").attr("onClick", function(index, currentValue){ return currentValue.replace(mode, modereplacement) ; }); 

        /*change Quick button*/
        $("#"+"all_"+currentgenre+'_cur').attr("onClick",function(index, currentValue){ return currentValue.replace(mode, modereplacement) ; }); 
        $("#"+"all_"+currentgenre+'_cur').prop("checked", (mode == "offx")); 

    }
}

And here is the HTML that implements the 'Check All' aka 'Watch All' buttons:

 <td><a  class='quickButton'>Watch All</a></td>
       <td><input type='checkbox'  id='alls_cur' onclick=\"watchgenre( $user_id,'All','alls', 'offx', 1);\" ></input></td>
       <td><input type='checkbox' $checkname  id='alls_fut' onclick=\"watchgenre( $user_id,'All','alls', 'offx', 2);\" ></input></td>

Thanks for any advice you are able to give
