could please provide link of page. anyway noticed json string not formatted. can validate @ http://jsonlint.com.

the keys should enclosed in double quotes

 [     {         "address": "727e 800n, 84321",         "data": "marker 1"     },     {         "address": "900e 800n, 84321",         "data": "marker 2"     } ]
