ADF Invoke operation manually from code

I want to execute a data control operation (CreateInsert and Delete) from a buttons ActionListener. I am aware a data control button can be inserted from the Data Controls menu, but for various reasons I need to do it this way, a prominent one being I need to perform extra runtime checks.

I found the following code:

      OperationBinding operation = bindings.getOperationBinding("operation_name");
      operation.getParamsMap().put("parameter_name", parameterValue);
      operation.execute();

But don't know which variables to use for myself. First of all, I don't know which binding I should use. Then, the operation name should, as far as I know, be CreateInsert, and for the next button, CreateInsert1. Thats whats used for UIBinding now (which I will remove).

The Data control I want to use the operation of is 'ARNG1'.

So in short, I need to know how to manually invoke this Data control's CreateInsert operation.

Thanks in advance.

Similar to Joe's answer but does not use EL Expression evaluator and uses direct access instead to get the BindingContainer

//Get binding container BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();

// get an Action or MethodAction
OperationBinding method = bindings.getOperationBinding("methodAction");
method.execute();
List errors = method.getErrors();

the code you want to execute an operation behind a actionlistener:

        public BindingContainer getBindings() {
          if (this.bindings == null) {
              FacesContext fc = FacesContext.getCurrentInstance();
              this.bindings = (BindingContainer)fc.getApplication().
                  evaluateExpressionGet(fc, "#{bindings}", BindingContainer.class);
          }
          return this.bindings;
      }

BindingContainer bindings = getBindings();
    OperationBinding operationBinding =
    bindings.getOperationBinding("doQueryResultReset");
    operationBinding.execute();
