 #### Attributes For Event Handling
 
 To handle events with html bindings just define any expression to listed event attributes. 
-If you defined an attribute for this events and defined callback function in sortableOptions at the same time attribute based callback will be selected.
-If attribute based callback expression is not filled then sortableOption based callback function will be selected.
+If you defined an attribute for this events and defined callback function in sortableOptions at the same time, the attribute based callback will be called first.
