[web2py] ajax:whats wrong with this

[Resa]

I having been trying to send variables in a function .. this function
that is being called is then suppose to receive the vars from the ajax
function.. can you help me .. because the ajax is not passing
theparameters to the function insert_updatedb




var time_per_question=2;                         //2 second to answer
one question
        var numBer={{=request.vars.number}};               // the
number of questions in worksheet
        var bonus= (numBer<20)? 1: (numBer<40)? 3 :(numBer<60)? 7:
(numBer<80)? 9: (numBer<100)? 11 :13    // calculate bonus
        var total_time=converttime();
        var mgp= (((correct/numBer)+(total_time/
(numBer*time_per_question))+bonus));
        {{=numBer}}=numBer
        {{=correct}}=correct
        {{=total_time}}=total_time
        {{=mgp}}=mgp
        {{URL('insert_updatedb',
vars=dict(numBer='numBer',mgp='mgp',total_time='total_time',correct='correct'))}}
        //ajax('{{=URL('insert_updatedb')}}',
['numBer','mgp','total_time','correct'],'');
