Remove Binding Context - SAPUI5

Question

Hello All,
I set a binding context to a viz-column-graph when I click on a datapoint. But now I want to implement a method where, on a button click(on UI) I need to remove the current context thats been binded to the graph.
My current code to do that:
onPress:function(){
flattened_dataset = this.getView().byId("dataset");
dataset.removeAllDimensions();
new_dimesion_prd_name = new sap.viz.ui5.data.DimensionDefinition ({name:"Product_Name", axis:1, value:"{Product_Name}"});
new_dimesion_year = new sap.viz.ui5.data.DimensionDefinition ({name:"Year", axis:1, value:"{Year}"});
new_dimesion_quarter = new sap.viz.ui5.data.DimensionDefinition ({name:"Quarter", axis:1, value:"{Quarter}"});
dataset.insertDimension(new_dimesion_prd_name,1);
dataset.insertDimension(new_dimesion_year,2);
dataset.insertDimension(new_dimesion_quarter,3);
var graph = this.getView().byId("graph");
graph.unbindElement();
flattened_dataset.bindData('Quarter');
But the unbindElement() does not work in my case. Maybe I am missing something.
Any suggestions on How to remove the current binding context on  a page or graph element etc.
Thanks in advance.

Just to be clear:
The oracle.adf.model.binding.DCBindingContainer (a.k.a. Binding Container) represents the pageDef file for the page/fragment. In a JSF page you can refer to it via the EL expression #{bindings}. As Puthanampatti mentions the Binding Container contains references to the other bindings in your page including Value and Action bindings.
The oracle.adf.model.BindingContext (a.k.a. Binding Context) is a parent class to all the DCBindingContainer instances in your application. In a JSF page you can refer to it via the EL expression #{data}.
Note it is considered bad form to attempt to access the DCBindingContainer of another page/fragment from your current page/fragment. This is because the framework doesn't guarantee the Binding Container for the other page/fragment will be initialized.
