Jquery .keypress on a dynamically added input

Question

I am currently adding an input via a .click event and then wanting to listen to any keypress that occurs on this input. However, the appended isn't firing any events after it is inserted (i.e. blur, keypress, focus). Does anyone have any suggestions? Thanks in advance!

$("#recipientsDiv").click(function(){
    $(this).append('< input type="text" id="toInput" class="inlineBlockElement" style="border:0px none #ffffff; padding:0px; width:20px; overflow:hidden;" />')
    $("#toInput").focus();
});
$("input").keypress(function(e){
    var inputStr = $(this).html();
    $("#inputCopier").text(inputStr);
    var newWidth = $("#inputCopier").innerWidth;
    $(this).css("width", newWidth);
});
$("#toInput").blur(function(){
    $("#toInput").remove();
});

I did try .keyup .keydown as well, they don't work.

Your keypress handler is only being added to the elements that exist when you added it.

You need to call the live method to add it to every element that matches the selector, no matter when it was added.

For example:

$("input").live('keypress', function(e){
    var inputStr = $(this).html();
    $("#inputCopier").text(inputStr);
    var newWidth = $("#inputCopier").innerWidth;
    $(this).css("width", newWidth);
});
