Updating Editor Content with Javascript

[suhailshub-arch]

$("#id_description").val(ui.item.description);

I am trying to edit the content of the editor like this. However, the editor side does not change at all. But when I click preview the correct output is shown. Is there any way to update the editor content programmatically?

var editor = ace.edit('martor-description');
editor.setValue($("#id_description").val(), -1)

I did it this way and it worked
