Leveraging the Angular Material 2 table component to showcase data fetched from the backend system according to the user's present location

This question is similar to another one about how to get the current location in Typescript and pass it to a backend, which was answered by libertyernie. However, this time I need help with integrating the current location into an Angular Material 2 table for displaying restaurant data from a Spring Boot backend. The tutorial on GitHub specifies that the data source must be observable to enable features like sorting and filtering. Unfortunately, I am struggling to make it work...

The scenario is as follows: I want to retrieve the user's current location (e.g., lat=123 and lon=123) and then pass these parameters to my backend API endpoint at

http://localhost:8080/api/search/location?lat=123&lon=123
. This will return a list of restaurants that I need to convert to an Observable format so that the connect() function in ExampleDataSource can function properly.

I have attempted the code below, but the datasource does not receive any data back:

(insert code here)

You can find the full code on Github: https://github.com/zhengye1/Eatr/tree/dev
