How to re-initialize tinymce on ajax load?

Question

TinyMCE

Loading the following code

function input_content(){
  tinymce.init({
    selector: "textarea.input_content",
    	language: 'ru_RU',
    	skin: 'alko',
    	height : 300
  });
}

Then the form with this code is loaded using AJAX

<div class="form-group">
  <label>Описание</label>
  <textarea name="content" class="form-control input_content"></textarea>
</div>
<script>
  input_content();
</script>

The first time tinymce is initialized normally, it does not want to reload.

Answer 1

add id="content" to the form
tinyMCE.get('content').setContent($value);

Answer 2

Before re-initializing, do
tinyMCE.remove();
