Modify display template title onclick

Hi Team,

I have made a copy of Item_Default.html and I want to modify the title href and onclick for each result item being displayed.

Already added code in 

AddPostRenderCallback(ctx, function() {
    $(".ms-srch-item-link").each(function() {
        var x = $(this)[0];
        $(x).attr('onclick', '#');//need to open pop up here
    });
});

but when I inspect the result item, the onclick has value javascript:void(0);

I am able to set href="#" but unable to override onclick 

In search results I have calendar items, and on click of the title need to open pop up here but somehow the onclick value gets updated with javascript:void(0);

Thanks in Advance, Jiniv Thakkar
