I use the code as follows:
$(\".reply\").popover({ content: \"Loading...\", placement: \"bottom\" }); $(\".reply\").popover(\"toggle\");
you can just pass the title as function
var content = 'Loading...' function dynamicContent(){ return content } $(".reply").popover({ content: dynamicContent, placement: "bottom" }); $(".reply").popover("toggle");
and then change the variable content dynamically.
