Jquery/Tinymce - Loading tinymce after ajax post

Question

So i have a page that submits a form using ajax and then on success reloads the data/form. When the page initially loads, tinymce loads just fine with the page. When i submit the form, the form reappears but its just a textarea and not the tinymce. I think I have to initialize the tinymce again on success but i have tried and can't seem to get it to work. My Code:

My code:

    $.ajax({
            type: "POST",
            url: "/form.php",
            data: datastring,
            success: function(data) {                    
               $("#formcontainer").html(data);
                tinymce.init({
                selector: ".Htmltextarea"
               });       
            },
            error: function(){
                  alert('error handing here');
            }
        }); 
});

I also have the tinymce.init on the parent page where the form loads via ajax. Again, when I initially load the form, all works fines, the Tinymce loads. It just when i submit the form via ajax and the success/data is returned that I get the submitted form but the tinymce is gone. How to I get tinymce after ajax form submit? Thannks.

Attempt also not working:

    $.ajax({
            type: "POST",
            url: "/form.php",
            data: datastring,
            success: function(data) {                    
               $("#formcontainer").html(data);
               tinymce.EditorManager.execCommand('mceRemoveEditor', true, ".Htmltextarea"); 
               tinymce.EditorManager.execCommand('mceAddEditor', true, ".Htmltextarea");  
            },
            error: function(){
                  alert('error handing here');
            }
        }); 
});

Try this:

$.ajax({
        // tinyMCE.triggerSave(); // uncomment this line if tinyMCE is giving blank response
        type: "POST",
        url: "/form.php",
        data: datastring,
        success: function(data) {                    
           $("#formcontainer").html(data);
            tinymce.EditorManager.execCommand('mceAddEditor', false, ".Htmltextarea");
        },
        error: function(){
              alert('error handing here');
        }
    }); 
});
