jQuery - reset change event

I'm using Input file, so when I upload an Image and then remove it, I can't upload the same image again, only another different

addimg:

obj2.on('change', function(e){
    e.stopPropagation();
    e.preventDefault();
    $(this).css('border',"4px dotted #bdc3c7");
    var objid = $(this).parents('.drop').attr("id");
    var files = e.target.files;
    var file = files[0];
    if (files && files[0]) {
        var reader = new FileReader();
        reader.onload = function (e) {
            $("#" + objid).find(".addCont").css('visibility', 'hidden');
            $("#" + objid).css('background-image', 'url(' + e.target.result + ')');
            $("#" + objid).find('.imgmenucontainer').css('visibility', 'visible'); 
        }
    reader.readAsDataURL(files[0]);
    }
});

remove: 

$(".custombtnremove").click(function(){
    var objid = $(this).parents('.drop').attr('id');
    $("#" + objid).css('background-image', '');
    $("#" + objid).find('.imgmenucontainer').css('visibility', 'hidden');
    $("#" + objid).find(".addCont").css('visibility', 'visible');
});

So I assume It has to be something with the change event

did you try that case?:

1. upload file A
2. remove file A
3. upload file B
4. remove file B
5. upload file A

if that works fine, you have to add in your remove event:

$(obj2).val("");

The cause is you don't change data to comparison with previous the same data...well event change is not fired. Solution: after delete - set data to empty and all should works fine. In your change event you can add an additional condition for "" val.

Empty your input file after you remove an image.

$(".custombtnremove").click(function(){
    //previous code here
    //reset input file
    $(obj2).val(""); //-> or obj2.val(""); if obj2 is already a jquery object.
});
