It's because you are importing the svg from a file. If you include the svg markup on your page your code will work.

See this Fiddle

I think this is because when you import it the svg markup isn't loaded on the page yet so it cannot attach events to the path elements.

I did find a answer on StackOverflow that does address this. What you have to do is attach a load event to the object that when fired will attached your click events once it has been loaded.

See this answer.

Try to use the object for event triggering:

$(document).ready(function(){
        $('object').on("click", function(){
            alert($(this).attr('id'));
        });
 });

If you embed your svg doc into an <object> element, then you have to check for its contentDocument property and make the searches from the documentElement there.

I don't know well jQuery, but I think it's quite lame about svg, and I don't know too much either about other libraries, but here is vannila.js code :

document.querySelector('object').addEventListener('load',function(){
    var p = this.contentDocument.documentElement.querySelectorAll('path');
    for(i=0;i<p.length;i++){
     p[i].addEventListener('click', function(){ 
          alert("Hello my name is "+this.id+"…")
        });
    }
});

Note that you'll have to wait for the object has loaded its data and that you're restricted by the same-origin policy
