How to return ajaxSubmit data?

Question

JavaScript

When using ajaxSubmit ran into some difficulties.
The code doesn't work. Possibly a syntax error. I'm trying to return data to an element with the class main_background. The function is called but no data is returned.
Where is the mistake and how to fix it?

$('.graph_control_settings').on('change', function(){
$("#graph_control_form").ajaxSubmit({url: 'actions.php', type: 'post',success: $('.main_background').html(data)});
return false;
});

Answer 1

success must be represented by an executable function, since it is a callback to the execution of sending data, in other words:
success: function(data){
$('.main_background').html(data);
}
