XML For New Custom Action

I am trying to add a custom action button to a tab on the ribbon.

I have the following XML in an elements.xml file in Visual Studio:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://ift.tt/sQmbje">
 <CustomAction
 Description="CREATE NEW ITEM"
 Title="CREATE ITEM"
 Id="{53801DF2-A778-4E93-8191-ACBC06C7D4DD}"
 Location="ViewToolbar"
 RegistrationType="ContentType"
 RegistrationId="0x010014D754C688D12A4FB4C811B4B4F67A5C"
 Sequence="0"
 Rights="ViewListItems"
 xmlns="http://ift.tt/sQmbje">
   <CommandUIExtension xmlns="http://ift.tt/sQmbje">
     <!-- Define the (UI) button to be used for this custom action -->
     <CommandUIDefinitions>
    <CommandUIDefinition Location="Ribbon.ListForm.Display.Manage.Controls._children">
      <Button Id="{10C2173C-537F-4D3D-8394-9ADB8486CEBE}"
      Command="{99AAAD72-4AB6-4EC0-8B5A-E3F194145A4D}"
      Image32by32="~site/_layouts/Images/MYSOLUTION/Create32.png"
      Image16by16="~site/_layouts/Images/MYSOLUTION/Create16.png"
      Sequence="0"
      LabelText="CREATE ITEM"
      Description="CREATE NEW ITEM"
      TemplateAlias="o1" />
    </CommandUIDefinition>
  </CommandUIDefinitions>
  <CommandUIHandlers>
    <!-- Define the action expected on the button click -->
    <CommandUIHandler Command="{99AAAD72-4AB6-4EC0-8B5A-E3F194145A4D}" CommandAction="~site/_layouts/MYSOLUTION/mysolutionpage.aspx?List={ListId}&amp;ID={ItemId}" />
  </CommandUIHandlers>
</CommandUIExtension>
</CustomAction>
</Elements>

But all that appears is the following:

And the button does not work when I click it.

How can I get the tab to display the correct name and the button to work when clicked?

Is it possible to have this XML automatically generated?
