My JS weird shit

window.onload = Initialize;
var Input;
var Output;
function Initialize()
{
    Input = document.getElementById("Input");
    Output = document.getElementById("Output");
    Input.oninput = GetEmotes;
}
function GetEmotes()
{
    var TempResults = [];
    for (var i = Output.children.length - 1; i >= 0; i--)
    {
        if (!Output.children[i].value.includes(Input.value) || Input.value == "")
        {
            console.log(Output.children[i]);
            console.log(Output.children.length);
            Output.remove(Output.children[i]);
        }
        else
        {
            TempResults.push(Output.children[i].value);
        }
    }
    if (Input.value != "")
    {
        for (var key in emotes)
        {
            if (key.includes(Input.value.toLowerCase()) && TempResults.indexOf(key) === -1)
            {
                var NewButton = document.createElement("button");
                NewButton.value = key;
                NewButton.innerText = emotes[key];
                NewButton.onclick = Paste;
                Output.appendChild(NewButton);
            }
        }
    }
}
