Cant call Jquery function in if loop

my first ever question pretty sure I'm being a bit daft here, but am a beginner and would appreciate your help.

Im working on a webpage where there is a html table listing several columns of data. When the page loads it runs a jquery script which counts the different types of "incidents" and plots them in another table which then another jquery script populates a graph. I have a third script (javascript) which after a button is clicked, runs an if loop, which looks at the data in the first column and if it does not match the criteria then the row is deleted.

So far so good, the issue is that I want the script which populates the table for the graph to run again, but Im not sure how to call it from my if loop.

Ive put the two scripts below, basically I want to call the 1st script in the second script.

<script>
$(function () {
    var NumFireAlarms = $("#incidents tr:contains('Fire Alarm')");
    $("#result").html(NumFireAlarms.length + " Fire Alarm");
    var firealarms = NumFireAlarms.length;
    document.getElementById("no_of_incident_type").rows[1].cells[1].innerHTML = firealarms

    var NumLockout = $("#incidents tr:contains('Lockout Out of Office Hours')");
    $("#result").html(NumLockout.length + " Lockout Out of Office Hours");
    var lockouts = NumLockout.length;
    document.getElementById("no_of_incident_type").rows[2].cells[1].innerHTML = lockouts

    var NumLockoutDayTime = $("#incidents tr:contains('Lockout Day Time')");
    $("#result").html(NumLockout.length + " Lockout Day Time");
    var lockoutsDayTime = NumLockoutDayTime.length;
    document.getElementById("no_of_incident_type").rows[3].cells[1].innerHTML = lockoutsDayTime

    var NumSensitiveIncident = $("#incidents tr:contains('Sensitive Incident')");
    $("#result").html(NumSensitiveIncident.length + " Sensitive Incident");
    var SensitiveIncident = NumSensitiveIncident.length;
    document.getElementById("no_of_incident_type").rows[4].cells[1].innerHTML = SensitiveIncident       
});

<script>
function filterForGraph() {

    var incident_category = document.getElementById("Incident_Category").value;
    var start_date = document.getElementById("start_date").value;
    var end_date = document.getElementById("end_date").value;
    var staff_type = document.getElementById("Job_Title").value;

    var i;
    var count = 0;
    var table_length = document.getElementById("incidents").rows;
    var TL = table_length.length;

    for (i = TL - 1; i >= 1; i--)
    {
        var category_column = document.getElementById("incidents").rows[i].cells.item(0).innerHTML;
        var date_column = document.getElementById("incidents").rows[i].cells.item(1).innerHTML;
        var staff_colunm = document.getElementById("incidents").rows[i].cells.item(8).innerHTML;

        if (category_column === incident_category)
        {
            alert("yay")
            count++
        }
        else if (category_column !== incident_category)
        {
            alert("boo")
            document.getElementById("incidents").deleteRow(i);

CALL FIRST SCRIPT HERE??

        }
    }
