Run Same Javascript Multiple Times Chrome Extension

I am currently injecting a Javascript file into a webpage from a chrome extension in order to auto-fill and submit a form on the webpage. Furthermore, I need this script to continuously auto-fill and execute the script. However, the form submission only will occur at the end of the script, forcing me to run the entire script multiple times rather than use a loop on the script's content. How can I go about ruing the same Javascript file over and over on a webpage? The method I am currently doing seems to fail and runs the script only once.

Here is my current background.js:

// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
executeScripts(null, [ 
    { file: "inject.js" }, 
    { file: "inject.js" },
    { file: "inject.js" },
    { code: "inject.js" }
])
});

Inject.js is the Javascript file that I want to run multiple times. Here is the simplified version of the script:

(function() {
   var text = "hello";
   var url = "www.google.com"

   document.getElementById('personaName').value = text;
   document.getElementById('customURL').value = url;

   var form = document.getElementById("editForm");
   form.submit();
 })();
