nuxeo-data-table not managing multivalued strings properly

Steps to reproduce:

• Create a custom schema in Studio

  name	type	Multivalued
  codigo	String	Yes

• Associate the schema with a document type
• Generate the view layout for the document type in View Designer
• This code is generated:

      <nuxeo-data-table items="{{document.properties.telcofactura_schema:codigo}}" orderable="true" editable="true" role="widget" size="0">
  
        <nuxeo-data-table-column name="Codigo">
          <template>
            [[item]]
          </template>
        </nuxeo-data-table-column>
  
        <nuxeo-data-table-form>
          <template>
            <nuxeo-input value="{{item}}" label="Codigo" type="text"></nuxeo-input>
          </template>
        </nuxeo-data-table-form>
      </nuxeo-data-table>
  

• Save changes
• Deploy on your instance
• Create a new document

When you try to add a new value nothing happens. This error is shown in the browser console:
