An expression is created via a framework based on input from a developer. The expression is received at an expression engine wherein the expression describes a relation between a first property of a first data of the application to a first property of a second data of the application. A binding is created between the first data and the second data based on the relation via the expression engine. The first property of the second data is changed based on a change to the first property of the first data wherein the changing occurs because of the binding. The receiving the expression, the creating the binding, and the changing the first property are orchestrated via the framework to manage when the expression is executed in the application. ## Claims ### Claim 1 A non-transitory computer-usable storage medium having instructions embodied therein that when executed cause a computer system to perform a method for dynamically binding data in an application, said method comprising: creating an expression via a framework based on input from a developer;
