function loadjson doesn't return anything

still not working :(

$(document).ready(function(){
    function loadjson(url,lang,next){
        if(next<=0||next=='undefined'){
            next='null';
        }
        $.ajax({
            url:url,
            type:'POST',
            data:{lang:lang,next:next},
            success:function(data){
                tpl(data);
            },
            dataType:'json'
        });
    }

    $('#tt').click(function(){  
        //var c = loadjson('/getLang.php','english',-1); 
        //tpl(c);
        // loadjson function does a ajax function. Generally ajax
        // function can not return anything, if the ajax call is asynchronius.
        // In that case you need to do in success call back.
        loadjson('/getLang.php','english',-1); 
    });
    
    function tpl(jdata){
        var tpl = "";
        console.log(jdata);
          tpl  = '<div class="form-group">';
          tpl += '<label><span class="label label-danger">English</span> '+jdata._default+'</label>';
          tpl += '<br/>';
          tpl += '<label><span class="label label-success">Key</span> '+jdata.key+'</label>';
          tpl += '<div class="bg-warning" id="_'+jdata.key+'"><p class="to-translate"></p></div>';
          tpl += '</div>';
        $('#tform').append(tpl);
    }
});

1. set header content type to json
   or
2. use parse json in javascript
