Trying to make Dogecoin extension, need help

coolgem923

Hey everyone,
I'm trying to make an extension that would check the confirmed balance of a Dogecoin address using the chain.so blockchain api, but so far I have little luck.
I'm trying to combine the ScratchX Weather API example here with the get balance API example here.
So when I import the extension into ScratchX, I get the

(balance [address])

block I add, but it never returns any output.

What am I doing wrong?

(function(ext) {
    // Cleanup function when the extension is unloaded
    ext._shutdown = function() {};

    // Status reporting code
    // Use this to report missing hardware, plugin or unsupported browser
    ext._getStatus = function() {
        return {status: 2, msg: 'Ready'};
    };

    ext.getbalance = function(location, callback) {
        // Make an AJAX call to the Chain.so API
        $.ajax({
              url: 'https://chain.so/api/v2/get_address_balance/DOGE/' & location & '/0',
              dataType: 'jsonp',
              success: function( balance_data ) {
                  // Got the data - parse it and return the confirmed balance
                  status = balance_data['status'];
                  balance = balance_data['data']['confirmed_balance'];
                  callback(status);
              }
        });
    };

    // Block and block menu descriptions
    var descriptor = {
        blocks: [
            ['R', 'balance %s', 'getbalance', 'address'],
        ]
    };

    // Register the extension
    ScratchExtensions.register('Dogecoin', descriptor, ext);
})({});

I'm not too familiar with the extension API yet but it looks like you should be doing callback(balance)
