Based on l2aelba anwser. This was tested on FF, Safari, Chrome, IE (8,9,10 and 11)

    $("#editText").on("paste", function (e) {
        e.preventDefault();

        var text;
        var clp = (e.originalEvent || e).clipboardData;
        if (clp === undefined || clp === null) {
            text = window.clipboardData.getData("text") || "";
            if (text !== "") {
                if (window.getSelection) {
                    var newNode = document.createElement("span");
                    newNode.innerHTML = text;
                    window.getSelection().getRangeAt(0).insertNode(newNode);
                } else {
                    document.selection.createRange().pasteHTML(text);
                }
            }
        } else {
            text = clp.getData('text/plain') || "";
            if (text !== "") {
                document.execCommand('insertText', false, text);
            }
        }
    });
