Implemented PHP callback support for on() method

Sample:
 $this->on('click','.button1',function($js){
   $js->val(rand());
});

MINDBLOWING!
Passing true as 2nd argument to ajaxec makes it read data from element

<div data-test="2" class="hello">

$this->on('click','.hello', function($js,$data){
  $js->univ()->alert($data['test']+2);
}

Will alert(4) after callback call
