});

   var $popover = $(".poper").popover({
    trigger: "click"
}).click(function(e) {
    e.$("#transbg").css("padding-bottom","260px"); 
});

$popover.on("hide", function(e) {
    $("#transbg").css("padding-bottom","50px");
});

The popover show event syntax is not correct,Can you try the following

HTML

<a class="poper btn" rel="popover" data-toggle="popover">
    <h3 class="gv layout">
        Layout Plan</h3>
</a>
<div class="popper-content hide">
    html
</div>

JS

var abc = $('.poper').popover({
    placement: 'bottom',
    container: 'body',
    trigger: 'hover',
    html: true,
    content: function () {
       return $(this).next('.popper-content').html();
    }
});

abc.on("shown.bs.popover", function (e) {
  console.log("popover shown");
});

abc.on("hidden.bs.popover", function (e) {
  console.log("popover hidden");
});
