IE not calling $.ajaxSetup
===

The following call works great in every browser but IE. `$.ajaxSetup` doesn't get recognized. The `error` and `complete` functions won't be called unless I add them directly into the `$.ajax` call.

Any idea why?

    function setupAjaxCalls() {
        $.ajaxSetup({
            type: 'GET',
            dataType: "jsonp",
            contentType: "application/json",
            data: {
                deviceIdentifier: deviceIdentifier,
                deviceType: deviceType,
                memberId: loggedInMemberId,
                authToken: authToken,
                cache: false,
                responseFormat: 1
            },
            error: function (x, e) {
    	        defaultError(x, e);
    	    },
    	    complete: function () {
    	        apiCallInProgress = 'false';
                //alert('complete!');
    	    }
        });
    }
    
    function logInForm(memLogin, memPassword, callback) {
    	apiCallInProgress = 'true';
    
    	$.ajax({
    	    type: 'POST',
    	    dataType: "json",
    	    url: baseApiUrl + '/MembershipService/AuthLoginSecure',
    	    data: {
    	        login: memLogin,
    	        password: memPassword,
    	        responseFormat: 0
    	    },
    	    success: function (data) {
    	        if (data.Success == false) {
    	            apiError(data);
    	        } else {
    	            loggedInMemberId = data.Member.Id;
    	            authToken = data.Token;
    		        
    	            if (typeof (callback) != "undefined" || callback) {
    			        callback(data);
    			    }
    		        
    	        }
    	    }
    	});
    }
