Flex: How do I access the data in my flex form and submit it to a ColdFusion cfc?

<mx:Form x="10" y="10" width="790" id="myFrom" defaultButton="{createReport}">
    <mx:FormItem label="Resume Report Type:">
    <mx:RadioButtonGroup id="showtype"/>
    <mx:HBox>
    	<mx:RadioButton groupName="showtype" id="NotUpdated" value="notupdated" label="Not Updated" width="100"  />
    	<mx:RadioButton groupName="showtype" id="Updated" value="updated" label="Updated" width="75"  />
    	<mx:RadioButton groupName="showtype" id="All" value="all" label="All" width="75"  />
    </mx:HBox>
    </mx:FormItem>
    <mx:FormItem label="User Organzation:">
    	<mx:ComboBox dataProvider="{qOrganization}" labelField="UserOrganization" />	</mx:FormItem>

    <mx:FormItem label="Between the following dates:">
    	<mx:HBox>
    		<mx:DateField/>
    		<mx:DateField left="10"/>
    	</mx:HBox>
    </mx:FormItem>
    <mx:FormItem>

    	<mx:Button label="Create Report" id="createReport"/>
    </mx:FormItem>
    </mx:Form>

var obj : MyObject = new MyObject();
obj.beginDate = beginDate.selectedDate;
obj.endDate = endDate.selectedDate;
obj.organization = Organization(comboOrg.selectedItem);
// etc
