I would put my form into the markup and not into some data tag. This is how it could work:
$('#popover').popover({
html : true,
title: function() {
return $("#popover-head").html();
},
content: function() {
return $("#popover-content").html();
}
});
<a href="#" id="popover">the popover link</a>
<div id="popover-head" class="hide">
some title
</div>
<div id="popover-content" class="hide">
<!-- MyForm -->
</div>
You might want to take a look at X-Editable. A library that allows you to create editable elements on your page based on popovers.
Mike Costello has released Bootstrap Web Components. This nifty library has a Popovers Component that lets you embed the form as markup:
<button id="popover-target" data-original-title="MyTitle" title="">Popover</button>
<bs-popover title="Popover with Title" for="popover-target">
<!-- MyForm -->
</bs-popover>
