blpraveen on "WordPress Editor switch between html and visuals not working"

I need to show the editor on my plugin dynamically. I tried using the javascript code to show editor

tinyMCE.settings = tinyMCEPreInit.mceInit.content;
  tinyMCE.execCommand('mceAddControl', false, textareaid);

But it doesnot show the upload and switch editors.

So I tired using an ajax in my javascript.
javascript

dataString = 'action=' + admin_object.action_editor + '&security=' + admin_object.action_editor_security + '&count=' + count;

    jQuery.ajax({
            type: "POST",
            url: admin_object.ajax_url,
            data: dataString,
            success: function(resultData){
                jQuery('.woocommerce_product_tab_wrapper').stop(true).css('opacity', '1').unblock();
                $div_group.append(resultData);
                $div_wrap.append($div_group);
                jQuery('.woocommerce_product_tab_wrapper').append($div_wrap);
                $div_wrap.css('display','none');
                tinyMCE.settings = tinyMCEPreInit.mceInit.content;
                tinyMCE.execCommand('mceAddControl', false, 'wptb_content_'+tab_count);
                switchEditors.switchto({'id' : 'wptb_content_'+tab_count+'-html'});
                jQuery("#wptb_content_"+ tab_count +"_ifr").contents().find(".qp").css("background-color","#00ff00");
                jQuery('.woocommerce_product_tab_wrapper .tabs').find('li.'+tab_title_slug + '_tab a').click();
                tab_count++;
            }
        });

Ajax function handler

public function get_editor() {
        check_ajax_referer( 'get-editor', 'security' );
        $tabcount = isset($_POST['count']) ? $_POST['tabcount'] : '';
        if(!is_numeric($count) && $count < 0) die();

        $settings = array(
            'quicktags'     => array( 'buttons' => 'em,strong,link' ),
            'textarea_name' => 'content[]',
            'quicktags'     => true,
            'tinymce'       => true,
            'editor_css'    => '<style>#wp-excerpt-editor-container .wp-editor-area{height:175px; width:100%;background:#FFFFFF;}</style>'
            );

        wp_editor( htmlspecialchars_decode( '' ), 'content_'.$tabcount, $settings );
        die();
    }

It shows me the upload and the switch editor. But now another error crops up. Initially editor is switched to html mode and buttons shown are visual. When I click the switch editor button to html the editor goes off.

Can any body help to show the editors by using the javascript.

Thanks
