An example of how to get Bootbox.js and Meteor playing nicely together.

meteor-bootbox.js

bootbox.dialog({
	title: “Modal Window Title”,
	
	/**
	 * Note in the following: 
	 * 
	 * "messages" needs to be a string of at least 1 character in length
	 * as it's required for Bootbox to function properly.
	 */
	message: “ “,
	buttons: 
		main: {
			label: "Done",
			className: "btn-primary",
			callback: function() {
				console.log(“Done clicked.”);
			}
		}
	},
});

/**
 * In order to get reactive templates to function properly, you have to
 * render the template after the Bootbox dialog has been instantiated.
 *
 * Parameters below that might need some explanation:
 *
 *	yourWindowTemplate – The template you want to render inside the Bootbox dialog.
 *
 *	yourDataContext - The data context for the template. 
 *
 *	$(".bootbox-body")[0] - This is the parent element where you're rendering your
 *	content. To get this semi-hack to work, this is REQUIRED.
 */
Blaze.renderWithData(yourWindowTemplate, yourMongoCollection.findOne(item_id), $(".bootbox-body")[0]);
