[web2py] Setting web2py-component-command

[Luther Goh Lu Feng]

I wish to run a script after a component is ajax loaded. To achieve
that, I attempted to set the web2py-component-command as follows:

======================
<!-- Reload comments component at regular intervals-->
comment_component = function(){
        t = $('#comment_text__row textarea').val();
        {{response.headers['web2py-component-command']="console.log('yay')"}}
        web2py_component('/roverus/comment/create.load?current_conversation='
+ current_conversation,'conversation');
}
setInterval("comment_component()", 5000);

======================

However "console.log('yay')" does not run.

I also set web2py-component-command in the related function as
follows:

==========================
function web2py_ajax_page(method,action,data,target) {
  {{response.headers['web2py-component-
command']="console.log('yay2')"}} <---------------------added line
  jQuery.ajax({'type':method,'url':action,'data':data,
    'beforeSend':function(xhr) {
      xhr.setRequestHeader('web2py-component-
location',document.location);
      xhr.setRequestHeader('web2py-component-element',target);},
    'complete':function(xhr,text){
      var html=xhr.responseText;
      var content=xhr.getResponseHeader('web2py-component-content');
      var command=xhr.getResponseHeader('web2py-component-command');
      var flash=xhr.getResponseHeader('web2py-component-flash');
      var t = jQuery('#'+target);
      if(content=='prepend') t.prepend(html);
      else if(content=='append') t.append(html);
      else if(content!='hide') t.html(html);
      web2py_trap_form(action,target);
      web2py_ajax_init();
      if(command) eval(command);
      if(flash) jQuery('.flash').html(flash).slideDown();
      }
    });
}

======================

This too does not work.

Can anyone enlighten me if I misunderstood the syntax, or is there
another way I can get this working? Thanks in advance.
