Page get redirected on Google Adwords Conversion Tracking

Question

I've form where people submit data and the data is sent to the server using ajax. I've setup this as a conversion in Google Adwords. Below is the code that I've used.

The problem is, when a user submits the form, after getting the response, its redirected back to URL that I've given. I don't want to redirect!!

(Data submitted is using Vue-resource since this project is in VueJS)

submit() {
  let self = this
  this.$validator.validateAll().then(success => {
    if (!success) {
      return;
    }
    document.getElementById("submitQuote").value = "Submitting...";
    this.$http.post(store.state.url+'api/submit_quote.php', {
        formData: store.state.formData
      })
      .then(response => {
        console.log(response.data)
        this.submitted = true
        self.reference_id = response.data
        goog_report_conversion('https://www.example.com/') //report Google that a conversion has occured
      });
  });
}

Just don't provide a redirect URL to goog_report_conversion, i.e. call it without parameters.

The redirect is conditional:

if (typeof(url) != 'undefined') {
    window.location = url;
}
