how to place JS-code to NewForm.aspx of a list in SharePoint 2013 APP.

In sharepoint 2010 we can use this list definition to add JS:

```
<List ...>
  <MetaData>
    ...
    <Form Type="NewForm" Url="NewForm.aspx" SetupPath="pages\form.aspx" WebPartZoneID="Main" UseDefaultListFormWebPart="False">
        <WebParts>
          <AllUsersWebPart WebPartZoneID="Main" WebPartOrder="1">
            <![CDATA[ 
            <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2"
                xmlns:sfwp="http://schemas.microsoft.com/WebPart/v2/SimpleForm">
              <Assembly>Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>                         
              <TypeName>Microsoft.SharePoint.WebPartPages.SimpleFormWebPart</TypeName>
              <FrameType>None</FrameType>
              <Title>JS1</Title>
              <sfwp:Content>ANY HTML YOU NEED HERE
              </sfwp:Content>
            </WebPart>
            ]]>
          </AllUsersWebPart>
          <AllUsersWebPart WebPartZoneID="Main" WebPartOrder="2">
            <![CDATA[
            <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2">
              <Assembly>Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>                         
              <TypeName>Microsoft.SharePoint.WebPartPages.ListFormWebPart</TypeName>
              <PageType>PAGE_NEWFORM</PageType>
            </WebPart>
            ]]>
          </AllUsersWebPart>
        </WebParts>
      </Form>
    </Forms>
  </MetaData>
</List>

```
