Keep on attempting to connect the client until it's not connected?

Hi guys I'm using MQTT.

```
export function establishConnectionApplianceConfig (client, uniqueId, callback) {
client.connect({
onSuccess:onConnect,
onFailure:doFail
});

function onConnect () {
client.subscribe('/home/'+uniqueId+'/configuration/get/response')
console.log('onConnectCalled')
callback()
}

function doFail (e) {
console.log(e)
console.log('Do Fail Called')
callback()
}
}

establishConnection (callback) {
console.log('wifi-id: '+this.state.uniqueId)
establishConnectionApplianceConfig(global.applianceClient, this.state.uniqueId,() => {
callback()

})
}

callback () {
if (global.applianceClient.isConnected()) {
getAppliances(global.applianceClient, this.state.uniqueId)
receiveApplianceUpdate(global.applianceClient, this.state.uniqueId, update => {
let status = JSON.parse(update)
console.log(status)
if (typeof status.power != 'undefined') {

} else {
getAppliances(global.applianceClient, this.state.uniqueId)
}
})
} else {
setTimeout(this.establishConnection(() => this.callback()), 5000)
}
}

networkScanning((searchObject, data) => {
console.log(data)
global.applianceClient = createClient(data)
this.establishConnection(() => {
console.log('Callback triggered')
if (global.applianceClient.isConnected()) {
getAppliances(global.applianceClient, this.state.uniqueId)
receiveApplianceUpdate(global.applianceClient, this.state.uniqueId, update => {
let status = JSON.parse(update)
console.log(status)
if (typeof status.power != 'undefined') {

} else {
getAppliances(global.applianceClient, this.state.uniqueId)
}
})
} else {
setTimeout(this.establishConnection(() => this.callback()), 5000)
}
})
```

The thing is Mqtt port 1883 starts first and it takes a while to start 9001. So I can detect detect MQTT but I can't connect to it so I was attempting to reconnect to it continuously until it's not connected. How to accomplish this? I'm open to any other alternatives as well.
