Append/prepend not work with load? And some questions

I have two problems with append/prepend on JQuery. My code:

function toselect(f,d){
    $('#workcont').remove('h2').load('pages/' + f + '.html #' + d).prepend('<h2>Some text</h2>');
    calculate();
}

Div on default is clear <div id="workcont"></div>

Problems:

1. prepend add code for a second and then disappears开发者_Python百科, why? (not hide! removed)

2. remove('h2') don't remove added by prepend code. (if prepared wil be work) It's some function in my .js file.

3. function calculate(); does not apply to loaded content. Use with live() also not work.

try prepend in callback

function toselect(f,d){
    $('#workcont').load('pages/' + f + '.html #' + d,function(){
    $(this).remove('h2').prepend('<h2>Расчет стоимости</h2>');
    $('#workcont').calculate();
});

}

load has a callback function , the reason is that load work async and hence the prepend add the html before load completes , you may try like this

function toselect(f,d){   

$('#workcont').remove('h2').load('pages/' + f + '.html #' + d, function(){

  $("#workcont").prepend("your html");
  calculate();

 });

}
