Have a problem in calling a subcontroller

Question

I try to use the model class and call a subcontroller class to display data in another view by using the following code.
<b>In the do_init</b>
    Create the model of this class
      l_model = create_model( model_id = c_model_id
                              class_name = lc_class_name ).
    Create sub controller
      l_controller ?= create_controller(
                                    controller_name = lc_control_name
                                    controller_id   = c_subcontrol_id ).
      controller_set_active( controller_id = c_subcontrol_id
                             active = 0 ).
      l_controller->set_model( model_id       = c_model_id
                               model_instance = l_model ).
<b>In the do_request</b>
    controller_set_active( controller_id = c_subcontrol_id
                           active = 1 ).
    call_controller( l_subcontrol ).
    clear current_event.
At the view of subcontroller, after any event occurs, the parent controller is triggered again. Why? How can I solve this problem?

I do appreciate your immediate reponse. However, there may be some misunderstanding. Of cource, I put the checking coming event in the do_handel_event. The details of my application is shown below.
<b>In the do_init method</b>, all source code is the same that I posted. It has creating a model class and then a subcontroller class.
<b>In the do_request method</b>, I have a code like this.
  <b>dispatch_input( ).</b>
  main_view =
        create_view( view_name = 'main.htm' ).
  l_model ?= get_model( c_model_id ).
<i>To separate tasks between calling a view and calling a subcontroller, I have to have a flag, <b>current_event</b>, to check whether the coming event is search. This flag is set at the method <b>'do_handle_event'</b></i>
if  current_event eq lc_search.
    l_subcontrol  ?=  get_controller( controller_id = c_subcontrol_id ).
    controller_set_active( controller_id = c_subcontrol_id
                           active = 1 ).
    call_controller( l_subcontrol ).
    clear current_event.
  elseif current_event is initial.
    call_view( main_view ).
  endif.
In the do_request of my subcontroller class, I call the view of the subroutine.
dispatch_input( ).
  l_model ?= get_model( 'mm' ).
  stock_view  =  create_view( view_name = 'stock.htm' ).
  stock_view->set_attribute(
                     name = 't_display' value = l_model->t_display ).
  stock_view->set_attribute( name = 'ITERATOR' value = me ).
  stock_view->set_attribute( name = 'show_popup' value = show_popup ).
  call_view( stock_view ).
After any event occurs in this view of subroutine, I catch this event at the method do_handle_evnt.
if htmlb_event is bound.
    case htmlb_event->server_event.
      when  'onSelect'.
        CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
        tv  ?=  cl_htmlb_manager=>get_data(
                                      request  =  request
                                      name     =  'tableView'
                                      id       =  'stock_tv_display' ).
        if tv is not initial.
          table_event  =  tv->data.
          row_index    =  table_event->row_index.
          if row_index is not initial.
            show_popup  =  abap_true.
          endif.
        endif.
      when  others.
    endcase.
  endif.
After the program run through this method, it goes back to the do_request of the parent controller, main.do. This is my problem. <b>I don't want to call the parent controller again. And, my application has already been stateful.</b> Is there any way to prevent it. I sincerely appologize if I couldn't catch what you said. But, please give me some suggestions to solve this problem.
