Gorilla Mux routes not resolving

So, I'm working on a simple RESTful API using Go and Gorilla Mux. I'm having issues with with my second route not working, it's returning a 404 error. I'm not sure what the problem is as I'm new to Go and Gorilla. I'm sure it's something really simple, but I can't seem to find it. I think it might be a problem with the fact that I'm using different custom packages.

This question is similar, https://stackoverflow.com/questions/28831190/routes-returning-404-for-mux-gorilla, but the accepted solution didn't fix my problem

Here's what my code looks like:

Router.go:

package router

import (
    "github.com/gorilla/mux"
    "net/http"
)

type Route struct {
    Name        string
    Method      string
    Pattern     string
    HandlerFunc http.HandlerFunc
}

type Routes []Route

func NewRouter() *mux.Router {

router := mux.NewRouter().StrictSlash(true)
    for _, route := range routes {
	    router.
		Methods(route.Method).
		Path(route.Pattern).
		Name(route.Name).
		Handler(route.HandlerFunc)
    }

    return router
}

var routes = Routes{
    Route{
	    "CandidateList",
	    "GET",
	    "/candidate",
	    CandidateList,
    },
	Route{
	    "Index",
	    "GET",
	    "/",
	    Index,
    },
}

Handlers.go

package router

import (
    "fmt"
    "net/http"
)

func Index(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "Welcome!")
}

func CandidateList(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "CandidateList!")
}

Main.go

package main

import (
    "./router"
    "log"
    "net/http"
)

func main() {
    rout := router.NewRouter()
    log.Fatal(http.ListenAndServe(":8080", rout))
}

Going to just localhost:8080 returns Welcome! but going to localhost:8080/candidate returns a 404 Page Not Found error. I appreciate any input and help! Thanks!

This is an updated version of my Router.go file, there is still the same issue happening.

Router.go

package router

import (
    "github.com/gorilla/mux"
    "net/http"
)

type Route struct {
    Method      string
    Pattern     string
    HandlerFunc http.HandlerFunc
}

type Routes []Route

func NewRouter() *mux.Router {

    router := mux.NewRouter().StrictSlash(true)
    for _, route := range routes {
	    router.
		    Methods(route.Method).
		    Path(route.Pattern).
		    Handler(route.HandlerFunc).GetError()
    }

    return router
}

var routes = Routes{
   Route{
	  "GET",
	  "/candidate",
	  CandidateList,
   },
   Route{
	   "GET",
	   "/",
	   Index,
    },
}

It appears that my project was holding onto old versions of the Router.go and Handlers.go files in the main src directory. By removing these duplicate files and re-running Main.go with go run Main.go I was able to get the route to be recognized.
