API to add or disable a button

I was trying to disable, add, or remove buttons.

"oTableTools": {
			"sRowSelect": "multi",
	
				"aButtons": [
				{ "sExtends": "editor_create", "editor": editor },
				{ "sExtends": "editor_edit",   "editor": editor },
				{ "sExtends": "editor_remove", "editor": editor }
			]
		}

I would like to be able to delete, add or hide the buttons but was unsure of what collection the belong to!

I was guessing

$(dataTable.oTableTools.('editor_create').update());

or

$(editor.oTableTools.('editor_create').update());

Thanks in advance.
