Infopath form to display close button

hi all,

I have created a sharepoint list where in the new,edit and display forms are customized to infopath forms, 

So i have created the new, edit forms successfully, successfully means the functionality is working absolutely fine, ie on the click of the close or save button the form is closed or saved respectively

But when i created the same button on the displayifs form, it does not show that button on the browser when i work on my list,

I cannot use the ribbon close button because in my other master page the ribbon is hidden

Thanks in advance
