A Function doesn't work with setTimeout

So the page loads, however a part of the page is fetched from the server, which loads up later, so I set up a setTimeout function, however after doing this the error comes up

Uncaught reference error: check is not defined

I also moved check function outside the setTimeout still no luck

When this is pasted without the timeout function in the developer console everything, the check function works fine.

setTimeout(function() {


    var getclass = document.getElementsByClassName('title');
    var containerlength = getclass.length;

    for (var i = 0; i < containerlength; i++) {
        var container = getclass[i];
        var jobid = getclass[i].children[0].innerHTML.trim().substring(0, 5);
        var fragment = document.createElement('div');
        var chk = "";
        if (localStorage.getItem(jobid) == 1) {
            chk = "checked";
            getclass[i].style.textDecoration = 'line-through';
        }
        fragment.innerHTML = '<input onclick="check(this){" class="jobs" value="' + jobid + '" name="' + jobid + '" type="checkbox"' + chk + '></input>';
        container.appendChild(fragment);

    }

    function check(ele) {
        //     alert(ele.name);
        var name = ele.name;
        var papa = ele.parentNode.parentNode;
        if (localStorage.getItem(name) == 1) {
            localStorage.setItem(name, 0);
            papa.style.textDecoration = 'none';
        } else {
            localStorage.setItem(name, 1);
            papa.style.textDecoration = 'line-through';
        }
    }


}, 5000);
