extjs return ajax response

I need to assign the ajax response to a global variable so that i can use it thoughout my application. The obvious problem is that ajax requests are async thus complicating things.

I have tried to initialize an object before the ajax call, then assigning the response fron inside the success but that didn't work either.

Any ideas?

var p = {};
loadLang('en');

function loadLang(code) {

     Ext.Ajax.request({
      url : '/LoadLanguage.html',
      method : 'POST',
      params :{'code':code},
      timeout : 250,
      success : function(response, opts) {
        obj = Ext.decode(response.responseText);
        p = obj;
      },
      callback : function(o,s,r)
      {
      }
  }); 
}

 var myValue={item:"pie"};

 Ext.Ajax.request({
        url: 'test.php',
        params: {
            id: 1
        },
        success: function(response){
            alert(response);
            window.myValue.response=response; //yay for global scope.
                            console.log(window.myValue);//This has to be here,
                           //else it gets logged before the call gets completed.
        }
    });
