Activity Date method throwing jQuery error

[hfaerber]

Getting the following error when trying to run the activity handler function on pageload. Method passes all tests that invoke it. Possible something syntactical since we are using jQuery?

jquery.min.js:2 jQuery.Deferred exception: this.activityInfo.find is not a function TypeError: this.activityInfo.find is not a function
